I've had mental health related issues since I was a kid and I've been in treatment/therapy on and off. Sometimes I feel good or okay for years, sometimes I just feel like falling apart.

A good period can last for months. During that, I usually feel like I could take on the world. I can get done a lot of work and get engaged in new projects. I just feel like I want to be on the go all the time and I enjoy that feeling. I can be talkative, think fast and I feel self confident. I also have trouble sleeping during such periods, 'cause my mind is too active and I can't put it to ease. Last time this happened, I was sleeping about 3 hours a night for over 2 weeks. It's nothing extreme though. Once, during one of these periods a friend of mine told me that I seem to be a workaholic, but other than that people usually don't notice there's something different about me. Also, when I can't sleep, I don't feel rested the next day. I feel like a dying crap, but with some coffee and the fact that I simply have to do well at work, I put on a smile and carry on. Other than being more productive, active and interested in work and new projects, I don't experience much else. I'm not impulsive, quite the opposite. I feel organized and put together. I also eat a lot less and I feel like I'm at a perfect control of myself and everything around me.

The lower periods are very bad though. Last time it happened, it lasted for about 2 weeks and I was feeling so much pain, sadness and grief that I was physically sick and hurting. My whole body and soul was hurting. I couldn't get myself to work and was not interested in meeting anyone whatsoever. I couldn't logically explain this feeling, 'cause my life was objectively going really well.

I also often have days, when I feel extremely restless, even angry for no good reason and yet I can't even get up from bed. Today is such a day and I'm so angry with myself. I woke with racing thoughts in my mind, I can't focus on anything and yet I don't want to do anything whatsoever. I've been binge eating for the past week or so and continued to do so today too. During my better days, I don't feel like eating at all, so usually I lost weight often to the point of being underweight, while at other times, when I feel sad or like I'm loosing control, I just binge eat on everything. I was also supposed to clean up the house and take care of myself, but I can't do any of that. I just wish I could put my mind at ease. People have been bothering me with tasks since this morning, so I just turned off my phone and facebook, so none could reach me.

Should I be concerned? Could this bipolar or just general moodiness?
