quarantine trouble and ex boyfriends

ever since me and my boyfriend broke up in January it’s been hard but after a while we started to talk a little and we’ve been talking a little through lockdown and we both know it was just to kind of let each other know we are friends but we haven’t talked in a while and it’s making me just miss some things with him even though, deep down, he was not actually a very good boyfriend so i’m just trying to remind myself of that so it’s making it hard to move on again even from just talking to him as friends. i’m struggling with a lot of mental issues at the moment and i can’t really help myself bc i don’t know what issues i specifically have because my mum refuses to acknowledge that i have any issues because she doesn’t want it to reflect on her so i’ve had to figure out a lot of stuff by myself and i feel really useless right now and just a waste of space and i’m just really worried about myself.

so does anyone have any advice on just how to kind of unwind and help to relax and also how to get over a guy without distractions from my friends (due to quarantine)
