I was 6' 0", 145 lbs. I hated being so tall, weak, and skinny. I was really depressed and life sucked. I read on the internet that one of the best things you can do it set goals for yourself if you want to get out of depression. So I set a goal that I would gain weight to about 170 and work out. Well for a few weeks I was eating more and got up to about 157 lbs. I could be wrong but it seems like when you are a little more than very skinny, you are happier. I weighed more and I was generally happier. It is like my body was chemically balancing itself and mentally I was happy. I can't explain this next part, maybe someone can help. For no reason, I got really depressed again and stopped eating. My weight went back down to 150 and to this day I weigh the same, feel the same, and am just as weak and skinny as always. Why would this happen? Did I have a relapse or something?
