I feel you. I have never had really positive experiences on most social media. I keep Facebook messenger for the odd message from my mom; I have LinkedIn for professional stuff. I have Talking Sober which is the only place I actually socialize online.
I used to be quite active on Facebook & Instagram but I’ve let them go and I don’t really feel any desire to go back.
To replace that I’ve developed friendships with some of the people I met in recovery groups, and some colleagues at work. I go for walks, I organize BBQs (safe! always safe 
), I do art at home. I’m not really missing anything from dropping the social media.
Try stepping back for a bit and see how you feel. If you combine that with some activity on Talking Sober and/or other online recovery spaces (for example, the list of groups Sassy has here; many have online options and you can leave your screen off at many meetings: Resources for our recovery) - if you do that you’ll probably reach some new insights about yourself.
One day at a time, and don’t crave alone
