Don’t want to be rude or dismissive. You’re obviously going through some tough times. But you’re pretty far from rock bottom. I’ve been a lot lower and there was no bottom there either.
I hope all goes well: You finish your PhD and put this breakup behind you. Therapy helps and you feel better about yourself.
But if it does take a turn for the worse here is my short advice: First of all, get good sleep. Second, limit or cut ties with people who want to see you fall, or talk to / about you as if you already have, regardless of who they are (even parents). Also remember that healing / rebuilding yourself takes time, but as soon as the derivative is positive time is on your side.
