damn, i feel you on that, i've just started to get out of that sort of stuff, and trust me, it's tough.
HOWEVER
you have the key right in front of you; you already know and are somewhat sure that's not true, my honest advice would be to just cling onto that hope as hard as you can.
if you find that difficult --and trust me, it can and probably will be-- try this method i tried myself: if you're so sure, try looking for solid evidence that might indicate that you're right, but once again, put a lot of attention on the 'solid' part, as usually, you will come to the conclusion that most of those 'signals' (or whatever name you might attach to that) were quite literally false flags, or over exagerations.
trust me, the change won't be instant, it turns out to be just like a lot of the good things in life; they just take a little while to come.
i'm truly wishing you the best, and if you ever need some help, or advice, feel more than free to send me a dm, best of luck <3
