What’s wrong with me?

What does it mean when you’re feeling like a burden to everyone even though you’re trying to please them and avoid bothering them?

I’m somehow feeling alone lately, and I have no idea how to change that. I don’t know, maybe I’m just a boring person. I find myself “begging” my friends to hang out.

My family doesn’t understand me either. I’ve been through a lot lately in my personal life as a 20 year old, I really need something to cheer me up, but it seems like nobody cares. I talked to my parents about it and about how I feel, I talk to my sister all the time as well, she seemed to be understanding but didn’t show that she actually cares. She got really selfish lately and she hurt me emotionally a couple of times so I think I lost trust in her as well. I don’t know what’s the matter with my mother also. She won’t help me out with anything. I might ask her for the simplest thing, and she’ll sigh and show that she’s not interested. She avoids complementing me, she always ignores me when I talk, whenever she asks me for a favour I rarely disobey. I don’t feel like she sympathises with me when I’m down. I don’t know what the problem is with her as well, and I really don’t want to believe that my own mother and sister envy me. And as of my brother, he’s 9 but he’s being a bit mean. All I do for him is help him have good manners because my parents have lost total control over him. He swears and hits people and he’s basically turning into a bad boy. He kicks my legs and says that I’m the worst sister ever and I’m the meanest in the house.

I’ve been a bit distant today, because I’ve realised all this and I’m trying to understand where I’m wrong and if I can change something. Maybe I’m doing something wrong, or something I shouldn’t have been doing. I just don’t know what to do anymore. Once you lose everyone, I feel like it’s hard to get them back.
