BPD problems

I just made a post in another group about this but I’m really stressing. I am constantly worried that my friends don’t really like me. Now I acted childish even though I do feel like I have good reason to feel that way. But I didn’t go about it well. But that feeling isn’t going to go away. I feel sick and I want to apologize but I don’t think I’m wrong entirely. Ugh. I don’t know. I give so much because I’m afraid of not having anyone. I give gifts, money, my time, my patience, and I shove my feelings aside to prepare them because I don’t want them to leave. But then I am left feeling awful and I can’t address my feelings without it being some big deal in a way that makes me look like an idiot.
