It also sounds to me like the meds side effects. At least i was like that on heavy meds.

But im sorry you have to go through this. And you guys should always try to follow a treatment plan. But get used to the thought that its maybe never getting better and your brother will never be the same.

While there is good treatment and people that get healed after a short time. This illness is incredibly diverse and a life long condition in a lot of cases.

That means your brother could need your help medical and financially all his life. So if you rly want to make sure he is safe in the long run....

You need to work on yourself instead and get a good job that makes up for the both of you. Focus on your own self improvement and career, so you can be there for him if things get worse when you both get older...
