Feeling anxious about mental illness

Hey guys. well to make it short , i suffer drom Derealization 24/7 for 6 years now and i have anxiety problem. i tried to taper off my pills gradually half a year ago because i felt great after 6 years of taking them and i became extremly anxious and when i started to take the pills again they didnt do much and i started to have side effects .. now i felt on and off now but in the last couple of weeks i feel weird .. i dont feel 100% here , by that i mean that i overthink and cant concentrate because of my thoughts (i also suffer from ADHD). And im extremly scared that i might be developing some kind of a serious mental illness .. i dont knoww why but i feel like my Derealization is extremely strong and it feels like something else.. Please respond thank you !

I think with these things they completely overy helm us so much so our life is threatened and it takes years to fix the damage because we are feeble human beings. However there are other aspects of your character as well, such great patience . endurance and humility. things u are not aware of. let these things grow in your life
