Darren had a real good idea there, its got to be wrong of him going throug your things, that may be away out of this roomate.
As for talking about your feelings with the guys, I woud let feelings out naturally, its got to be hard, this I guess is easier said then done. I might test the waters a little and they seem sorta skiddish, maybe there will be at least one you can really click with and share how you feel.
Or/and you can also come here and talk, everybody is really supportve, will listen, you can vent
just talk, we are here.......
