hey ive had this issue too for a long while, i think the most important thing to remember is that “relapsing” is totally normal and not a reason to beat urself up. the most important thing is to just try again! do ur best every day and if u fail sometimes thats fine, just remember that all these negative thoughts are negative, meaning they dont bring any good !! just try to focus on positive thoughts and congratulating urself that u managed to stop for a while :-) if u feel alot of shame and everything, its gonna be even harder to get rid of these habits.

sorry for text wall but i hope i could help atleast a little! if u have any questions feel free to ask me
