Yes rose is right. You can always get your own place and be an introvert there. You need to find independence. I remember when I was your age, I lived alone and I was wild. I have regrets but at least I can say "been there, done that". Now I'm 29 and quite the introvert lately. I can't work right now because of my MI and I depend on my bf and only leave the house when I really need something. It's a crappy feeling to NEED someone at this age ya know? You deserve a life of your own and I'm sure if your parents ever needed help then your siblings would step up. I also know what it's like to be in the shadow of a younger sibling. My little sister is thriving in ways I never did and I'm the black sheep of the family. She too resents me and says nothing's wrong with me blah blah. I get it. You have an income... Can you move out?? Maybe look for financial programs for your parents like rose said and get yourself some therapy.
