Depression?

About 10 years ago I lost 70 pounds.  I have seen different doctors, had many blood tests, endoscopy of my stomach, and everything came back fine.  One doctor mentioned that I see a therapist.  Now that I am 27 and still havn't gained any weight back it makes me wonder if the reason to my weight loss was a mental thing.  I do know that when I get stressed out, anxious, or depressed I don't feel like eating and my appetite goes away.  But I do not really think I have a huge depression issue.  From time to time I get in these slumps, mainly in the winter time though.  Also, when this first started I always felt nauseaed, and the nausea didn't go away completely for about two years.  I am male, 6'1, and 140 lbs.  I will get depressed from time to time about being so skinny now, and also have a huge self esteem issue because of this too.  So, the all the doctors say there is nothing physically wrong with me.  Could there have been or still be something wrong with me mentally, like depression?  I do lose interest in my hobbies from time to time, but it doesn't seem too abnormal.  After 10 years of this and barely eating anything, I can't eat much any more now, so it makes it extremely difficult to put back on the weight.  Looking back to the beginning of this I don't think I was depressed at that time, just possibly stressed out from some things that were going on.  Would this be a possible cause of all this weight loss, 70 lbs?  Oh, by the way, all this weight loss is unintentional, I hate being skinny, I want to gain those 70 lbs. back and fast.
