My best friend is going through a rough time. I've always tried to be there for him in the past, but right now, I need a break. I'm a very introverted person and I get tired from social interactions, and this week, I've done something every single night. Seven nights in a row of being out, in loud environments, around people. I'm completely exhausted.
My friend keeps texting me that he needs to hang out, with wording like "Please? I need this". I feel selfish, but he often does this to me and I always end up getting (irrationally) angry and just avoiding him entirely for a few days. That's what I did last night, instead of explaining that I had yet another obligation already. But I don't feel like it's fair to just leave him hanging, especially since he's depressed. At the same time, I feel a lot of responsibility, like I'm his only source of social interaction and that if I don't talk to him when he "needs" me, he might kill himself or something, which makes me kind of resent him even when we do interact.
Don't get me wrong, I do love him and like spending time with him. But I often feel manipulated into hanging out when I would really rather be alone, and that's when I resent him. I feel like I have to ignore my own mental health to look out for his, and that's not fair to me. Is there any way to tell someone "I need my space" without being hurtful?
