It seems to me that the sleep situation is the easiest solved. anyway to find a bigger bed, or move a creature off? easier said then done, I know. Still not sleeping well can really screw you up moodwise.
Hang on about the friend. wait until you really have cooled. Unlessyou have talked to her you don't really know whether you have lost her or not. From your last post, it sounded as if you can save this if you want. You might have to save it on terms that aren't completely yours, but that is how relationships usually are. at the same time, don't make all the compromises yourself.
That's all I can say right now. I realy hope that this funk lets up Turquoise sea. You have so much of life to live, you know? Huggs and get some Z's.
