Oh yes. I understand the feeling. I still live in the house with my sister and I swear some days I could just lose it and beat her... I'm doing my best to hang in there, but you're absolutely correct, it's tough. I've learned that sometimes the best thing to do is to just be quiet and walk away, to do something you enjoy (something healthy and stress-relieving, of course) and just be. Listen to music or call a friend/relative you trust and have a heart to heart, or just talk. It can really help to get your mind off of things. I would also recommend getting into therapy if you aren't... I wasn't exactly thrilled with the idea originally, but it can be helpful.
