anyone else still struggling to let fears go?

i’ve always been an overthinker tbh but i honestly think it’s gotten so much worse since finding out about the loa? like i think i’m getting better but i still find it very difficult to “let go” or forget about things that have been bothering me for weeks because there’s still this like fear of letting go because i’m so used to coaches saying that if i let go, i’ll manifest. now i don’t believe in this stuff anymore, but part of me is still scared no matter how insane / unlikely my fear is and it’s most likely trauma or something at this point because this whole concept’s been messing with my mind but i can’t seem to fully let it go. i also spoke to a friend about my current issue and he told me that if he was in my position he would not be worried at all because i already got confirmation that i’m fine (from a professional) and he never even believed in the loa to begin with, but for me it’s like i have the need to “undo” all the overthinking i’ve been doing for the past few weeks and replace it with positive beliefs so i don’t accidentally manifest it. so annoying!! does anyone else still struggle with this?
