Avoidance, TW: Depression talk

I've noticed that I've been struggling a bit with avoiding the people around me, especially within my personal life. Not because I don't love or care about them, but because it can feel like a lot to talk sometimes. Especially with having a group of friends, I also am very avoidant of my family. I adore and care from them all, but sometimes the social interaction stresses me out more than it can be fun. My family always calls me rude or selfish for not talking to them, but I physically can't handle being around them sometimes. With my friends, I'm there as much as I can be. I never wanna make my friends feel bad because I'm not up to hanging out sometimes. I also don't want them to feel bad that I suddenly seem absent from their lives. I just wanna exist in a low-energy space, something calm. I don't want to have to talk or watch something or play games all the time. I just wanna exist sometimes. I don't know if that's selfish or not. I don't feel like it should be. I care about everyone and wanna be there as much as possible, but it can be hard in a space where I feel like I have to be my hyperactive self, otherwise people think I'm upset. My friends are great people, it's just I get so overwhelmed by the loudness of everything plus my own thoughts. I don't know, but hopefully I become less avoidant in the future.
