Hmmm, if your mom is never happy than that probably isn't a great place for your daughter to be living. You may want to bring her back home, no matter what the situation is(unless of course she's of age).
I don't know why you and your mom don't get along but just remember: you can never change her, but you can ALWAYS change the way you act and react to her. You never know, that just may help your relationship quite a bit. You said they are uneasy around you, do you have a bad attitude and not realize it? Anyway, I've been through some sticky situations w/ my mom also, and one day I realized I was putting too much emphasis on things that didn't even matter. We disagree on quite a bit but we get along just fine now because I realized, the things we don't agree on, we just should'nt talk about those subjects. Sometimes my mom gets mad and tells me to quit telling her what to talk about and sometimes when I'm in one of those wanting to argue moods :)I'll talk about a touchy subject w/ her, but for the most part we get along great. Life is too short to have hard feelings toward a family member, so ask yourself if what you are arguing about really matters. Focus on the things you love about her and don't talk about subjects that you both disagree on. Good luck and I wish you happiness!
