Hi, OP. I am dying and I am mid thirties. Creep the history.
I am on hospice, so my life has pretty much come to a screeching halt. My friends' lives? They have not.
My point is, I am literally dying and there are folks who can't make time for me. And it isn't a rejection! Because it is about them. Not you.
I am telling you this not because your feelings aren't valid, but because other people don't exist in a vacuum. You can love somebody and not reach out, even if they are mid crisis like me.
I bet if you sent some of them a message letting them know you were struggling instead of ignoring them for a month, they would be glad to hear from you.
