When I was in recovery, having no clue about psychosis, I tried my best to find accounts to help me know I would survive it; and it was always VERY hopeful when I did. I hope this account of recovery helps whomever is in recovery themselves.
Still Manic
First, when I was manic from having taken the Prednisone, this state lasted for a few weeks after having taken the last dosage. I felt, even after the arrest, that everything was just perfectly fine. To say I was clueless is an understatement beyond what I can express here. I remember having some very bizarre ideas, and one day I will post more. But briefly, the mania ended in a sort of step-down approach, and then a total depression took hold, but a sort of manic depression. It was a very dangerous period, and I am lucky to have survived it. I will just say that extremely dangerous ideas of self-harm came over me, and they seemed like the only way to escape the complete feeling of having lost my mind. Anxiety yes, but mixed with delusions and depression. It's was terrifying.
Oddly, I didn't even understand this at the time. I do remember talking to a therapist very early on, and ranting on and on to him, to which at one point he stopped me and said, "You are not okay. Does it feel like your mind is a shattered mirror?" I remember hearing this, and wondering what he was talking about. Soon after the bottom fell-out, and I found myself crying for about 4 days straight, uncontrollably and without end. I started to notice elements of my mind were at odds with each other; I could sense a buried voice "hiding" from a much more enraged one. And for weeks, I sort of just survived this.
When I began to come back to my mind, recovery was, oddly perhaps, not anything I was thinking of, and I do think institutionalized medical care is 100% needed for people in this state. As I said, I am lucky to have survived this period, and made attempts to ensure I wouldn't. At one point, I actually jumped out of a moving car.
Recovery
Here is what I did.
To start the idea was to calm down, and the only way I found I could do this was to listen to music. Ambient Music. I could not sleep, and would listen to this type of music to allow me focus my mind as best I could on the music. This was perhaps the biggest single thing I did to help myself.
Sleeping was a major issue, as was waking up in the middle of the night in complete panic attacks. When this happened each night, Writing a Journal, was very helpful. I would often start writing just to calm myself down, and much of what I wrote (looking back at it) makes no sense. But it did help me make sense of what was happening at the time.
The Bible. This may not be a popular idea for some, and before all of this, it wouldn't have been for me, however, do not discount the wisdom of the bible to help one navigate rough waters. I don't care what anyone says, if you haven't been through the anguish of tragedy (or psychosis), you don't understand, so if whomever you know is finding some sort of spiritual resource helpful, accept that it is helpful.
Walking. Although I could not do this for more than an hour at best without becoming totally exhausted, it was very important. As odd as it is, I found taking a walk to the cemetery helpful, as if I broke down crying, I could sit on a bench and no one would think much of it. But being outside also sort of helped bring my mind into an immediate reality rather than being coopted up inside.
T.V. This was also helpful for a mental escape. I would watch an old private investigator show, and sort of religiously follow along. I am not sure watching T.V. all day is a good idea, but I did come to enjoy watching this one show. I think it served as an escape, and still rather mentally unstable, I really did begin to identify with the show. I think it helped.
Talking with Others. This was very important, and likely it was most important to talk to someone as soon as I woke in the morning (normally really early.) Looking back, when someone is trying to recover, it seems to be that they (I did) need a daily reminder of what reality is. So if you are helping someone recover, and yes it will become VERY repetitive, but just allow the person to talk, and remind them they will recover. You may get a 4 am phone call, but please be patient. This, as it was in my case, might go on for a year. The only thing someone recovering from psychosis needs, is for them to know someone cares, and that there is hope.
Focus the Mind. When the time comes, you will have to come to focus your mind. How you do this is up to you, and in my case, I began to study Spanish. At first, I was just writing out the language without understanding, but overtime, my mind began to focus. A language is a very low-impact idea I think, and can be done at a local library in the silence you will likely need anyway. The accomplishment months into this study is also something to be proud of, and real. I also began to play golf. Again to focus the mind, and depending on the day and how you feel, you can play alone or with others. It's also a low impact sport, and can be made inexpensive if you do it right.
Continued Odd Actions. For me, and perhaps this is advice for the people impacted by the psychotic person, for a long while, I truly could not be reasoned with. I still, for a long while, had odd ideas come into my mind (like a worldwide letter writing campaign of some sort, travelling to distance places, living in a van... at one point I had an fascination with pens, and also started collecting due-date bag clips from loafs of bread, etc.) I would become very upset if challenged, so it's a balancing act on how to deal with this; I can now fully appreciate it, but did not at the time. For the person recovering, if ideas you have are being challenged, in all likelihood, they are not good ones. That said, you will need to do what is needed to recover, and many won't understand that either.
So then, there is also the obvious concern of not surrounding yourself with people who think psychosis is something you can "snap out" of, and just want you to rush back to normal life. This will not happen. The best thing to do is listen to experts in mental health; just listen to them as hard as it might be as they have seen psychosis before, know what it is, how people recover, and will offer an outside, professional, reality of the situation. Accept what they tell you! I won't offer any medical ideas, other than to say that.
I hope that helps. And good luck, you'll make it! There is a contact form on the three bars if you wish.
