need some help

whats up guys what are some tips dealing with ocd and what to do when a thought makes u anxious ??

so i was on instagram and it came up with other signs of ocd then someone commented this doesn’t mean you have ocd now im stressed that its not ocd background - i had so-ocd for a few years then got treatment for it but am now on the waiting list for further treatment for other stuff but i dont have another theme which makes me feel like its not ocd my day to day life consists of touching the door handle every time you go past it or someone will die, and inability to send emails without re reading loads of times and getting other people to check because im scared i wrote something bad but the what if it’s not ocd thought is triggering me now and i don’t know what do

i feel like i have been posting a lot about this and i will try to stop since now but i just don't know where to start or what to do, and i can't take therapy right now either. my event is about something that did actually happen; i had a boyfriend and we had a 1.5 age difference (i know this sounds stupid) but the thing is that we both started to sext a lot since he was 14 and i was 15. we shared audios videos pictures ect and i don't know how to just let this go, even when i know that i never really forced him into anything and i was always constantly worried about him being comfortable, when to stop and ect. the memories keep coming back to my mind and the guilt is eating me up slowly because i keep thinking that i'm a predator or a groomer or something like that. i don't know how to deal with the what ifs either, lately i haven't stopped thinking what if i sexually harassed or sexually exploited him or something like that. how do i deal with the cycle of guilt and constant what ifs if i also feel like my event is worse than others i've seen? please help me with this. it's getting a lil tiring and even if somedays i know how to deal with this, i still get really triggered sometimes. this wouldn't even bother me before, i wish i could just get back in time before this theme popped into my mind. my life has been a hell since then and i live constantly scared and suicidal.
