Recent panicking

I haven't had anxiety for a long time since I learned how to cope with it. Occasionally, however, sometimes it likes to make me not want to do anything at all for fear of others hating me for whatever it was, even if it was as simple as eating a cupcake. I would like to think that stems from a list of very...abusive people in my life before. some even I can't get rid of but have to deal with. Some of the things I learned that trigger me are Self-harm, Judgement, and failure (My biggest fear). I know better now what it is and how to deal with it as I've said before though it's very challenging.
