Cq1, it might take a while before you can be calm enough to be friendly. when I was first starting DB I lost my composure way more often than not. I always took responsibility for those times, usually apologizing by text to keep myself from losing it again, and then staying away as much as possible till I felt like I had more self-control. This is harder when you're still living together. Try, if you can. It does make a difference.
Best to you!
