Depressed when at parents' house, no matter what's going on?

I spend part of the time at my parents' and part of the time at my boyfriend's (I'm inbetween jobs and am having problems with school). Whenever I'm at my boyfriend's, I might get upset every once in a while, but he usually makes me feel better in no time at all. But when I'm at my parents', its like I'm constantly depressed and miserable. Now, they used to argue a lot, or say insensitive things to me. I think that played a big part in me being so depressed and insecure. Its not so bad anymore, but even when things are going good, I still feel depressed. Is it possible just simply being around them brings the depression out? Also, I can't really be my true self around them, and its different when I'm with my boyfriend. Plus, I have been suffering from depression and anxiety for about a year and a half now. I guess I'm just really looking for some things to make staying with my parents more bearable, and I'd like some suggestions...
