im actually so "groomable" it hurts (TW)

i hate being so vulnerable. all the time adults or older ppl take advantage of me because im socially stupid. my sister, a priest and some online people did this so far. they tell me smth sweet, i trust them, and then they manipulate me into doing things i dont want to. my sister tries to enforce wrong beliefs on me (racism and extreme religion, the priests call me "potential wife or partner" despite them being over 50, stuff like that.

how do i leave this cycle?
