Hey man, I have the same problem. I have severe depression and I get like that pretty much every single day. I have a girlfriend and she gets super upset when I don't talk to her about what's wrong. I told her it isn't her it's just me, but she still doesn't understand. It's really hard to explain it to her. I don't know of any solution. I get so depressed that all I can do is go to bed. Still, it doesn't help any. I don't know what to do but the whole thing makes me want to die a lot.
