Lately, I've felt very uncomfortable. I sleep very little and my rythm is very unstable, and at night, I don't feel like sleeping. I feel it is uncomfortable going to bed. I feel just living is uncomfortable because I have this feeling that I am running away from something is chasing me recentlessly. I've felt this especially today, but it is almost never ending. I have it in the back of my mind almost all the time, especially when I'm alone, and my nerves are like almost if I was in a combat situation. I thought that I might feel this especially today because I was drinking yesterday, but it is like this even if I don't drink (which I rarely do). I've also had this guilt trip. I feel guilty almost for everything. Is this some sort of disorder? It's driving me nuts. Help?
