This happens to me way to often. As a therapist between friends this is all too relatable. Adding with extreme heartbreak it does feel like so much. I wanna stop, but I can't. I'm the glue holding everyone together, and if I fall, them so does everyone else. Here's my advice as a semi sane therapist between friends: Try to find peace in being alone. Maybe meditating will be your thing. That's what I do, but find peace in being alone. Once you do that, it'll be a lot better. Trust me.
