Wa `alaykum as-salamu wa rahmatullahi wa barakatuh. 

I can tell that you have all the faith in Allah the Almighty that any person should be happy about it and try to maintain it insha’ Allah.

If such thoughts and reactions are because of the illness you are in especially it is a type of mental illness, I believe Allah the Almighty will not hold you responsible for it because illness is one of the categories of exemptions in Islam.

Allah Almighty knows best.
