Do have any toxic family members?

I actually just came home from a year and a half of living as a traveler. My family has always been a bit overly ignorant and depressing. I keep getting shakes in my body like I am about to do something crazy about it. I wont but I need to know that option is available. It's shitty. I just can't wait to get my liscense back so I can actually have a place I can call mine. I sleep on the couch and I just never felt like I belonged here. Eversince I was about 15 16 I'd have friends houses I'd stay at. I don't have that option any more. I am kind of stuck with a house that see's the cringiest shit. I do feel for them, a lot. They have so much to learn and I have a big role considering I am the oldest sibling. It's impossible to be myself and them not to get offended.
