I'm 22 and live at home with my adult brother and parents. I always struggle when we have people over, like if my parents have friends round I will tend to stay upstairs. I don't know why; I'm shy and I guess I just feel like a burden and that they won't want me there. My brother has had a few girlfriends who he has stay over, and I find it really difficult to meet them. I tend to avoid meeting them as long as possible, and I've only met one of 4 of his most recent girlfriends.
He has a new girlfriend and my parents have obviously met her, but I haven't yet. I know it's really rude, and my brother and parents tell me so too, but I find myself deliberately doing things to avoid having to meet her like jumping in the shower, pretending to be unwell or going out. It's nothing against her, but I just feel like I'd be a huge letdown as a potential sister-in-law. They are always beautiful, successful, outgoing, etc. Whereas I'm the complete opposite. I'm not sure if it's because I don't have any sisters so I just find the idea intimidating. I'm so embarrassed and frustrated at myself.
I can't afford to move out as I've recently been made redundant.
