I am a full time student and employee, I'm never home unless I'm off work and even if I'm off I go to the gym, or sit in my car to avoid my family...I've made a habit out of staying up late to avoid them and have alone time.

Today my brother in law lost it because I parked in his "spot" we recently moved and the place we move in has 3 spots for cars, we own four cars. I've been parking in guest parking where we are not supposed to and we can be fined or get our car towed. My sister was only thinking about her self when she bought house. Being that I am usually the last person home I park in the guest parking. Today I came early and my brother in law was upset he Didnt have a spot he was cussing at my sister and taking about how i purposely parked there to annoy him. And I'm thinking to my self am i a piece of shit do i not deserve to park where i live? He asked my sister to tell me to move my car I said no. There's been numerous occasions where it seems like I'm just extra and not important or less. I think it is mainly because my sister took me in in 6th grade (I'm 20 now) and every second and every annoying comment makes me wanna move which is not the most rational thing for me to do right now. Even my sister treats me like crap she has a issue with everything I do. we dont even say hi to each other when we see each other for the first time during the day, I avoid sitting next to her at dinner because I feel awkward. They actually moved in to the new house without telling me and I slept at the old one for a couple days without furniture. And Its like what do you want i dont bother you, I'm not doing drugs, I'm not acting crazy, im just working and going to school. I honest felt like crying because I dont know what to do. They just got married a year ago

Edit: my sister is annoying to her own kids too and super crazy should I just ignore it, shes been like this to me Since 6th grade.
