Dear Omega5,
You're not completely, entirely alone, because we're reading your post(s) and thinking about your stress and stuff, even if we don't post a reply.
oops, just re-read your post. You feel alone but you know you're not. Actually, I know about this. When I'm depressed, I can't feel that anyone cares about me. It looks as if they do but I can't feel as if I'm cared about. It's a problem with the depresssion for me.
Sorry to hear you're stressed out. (((Omega5))) (lots of hugs, if you want them!)
