I’m so sorry to hear of your situation mate. Can you do any light exercise? might help with your mental state. At least you’re getting good support from your family? Is there anything that helps take your mind of the situation? seems to help me allot. Its important to remember that none of this is your fault you were prescribed this drug at such a young impressionable age.
I can’t guaranteed you’ll ever be 100% the same but you’re Young and should be optimistic that you can improve with time, and be able to live a good life. There are allot of stories of people improving with time on this site, and rarer but not uncommon full recoveries. I think you should be looking forward to seeing Dr Jacobs he sounds like a great doctor who will take your situation very seriously. You have many treatment options to explore. How are your other symptoms are you sleeping OK? That could be making allot of the mental issues worse which is half the battle.
