I'm sorry you're hurting so much and I wish I could come up with an easy answer. I don't know if something happened to you recently, or if it's a pattern of feeling sensitive and easily hurt. I've always been a very sensitive person and one thing that helps me is accepting that as part of who I am. Our society tends to equate sensitivity with being weak, but often sensitive people simply feel things more deeply and have a very strong sense of empathy. Have you heard of Highly Sensitive People? If not you may want to read up on it.
