Thoughts are powerful but they are pointless

I'm getting intrusive thoughts of self harm. It seems like I've achieved everything in my life and it makes little difference. None of it was worth anything.

I’m trying to let them pass not engage nothing , trying to compusle but the thoughts won’t leave. My brain keeps telling me I should stab my dad for not asking if I’m okay after the death of my ex …

Believing in God is also a matter of faith. Believing that thoughts have power is also a kind of faith. But people say we should believe in God — then why shouldn’t I believe that thoughts have power too?
