I have a form of dissociation, what is the advice for Muslims who suffer from psychological disorders? I don't know why I have it and from what I've searched there isn't really a treatment for it right now. I pray all my prayers but I still know that my condition effects the use of time outside of that. Also the thought of trying to force myself to not be this way is also distressing.
Mental disorders are like any other illness. God holds us only responsible for what is within our power, so if a mental disorder makes it more difficult for us to carry out our religious duties then God will not blame us. And if it is more difficult for us to do good deeds and we still do them, our reward will be greater, since God rewards us according to our efforts and sacrifices. Imagine the most intelligent and kind person you can ever meet and how they would think of you and your condition. God’s view of you would be similar. Know that He understands you, sympathizes with you and does not expect you to be perfect.
Dissociation can be caused by a history of trauma during childhood or later. See The Body Keeps the Score by Bessel van der Kolk, who also mentions many unique options for treatment that are not widely known. Try to research your condition and perhaps you will find treatments that work.

Best wishes.
