Is this Anorexia?

I am 5'7, and 100 pounds. Most of the people in my family are small, women between 105-125 pounds. I've used this an an excuse for a long time, for not eating. The truth is, I do not get hungry enough to eat more than a couple of times a day. I'm a mom of five, I work 20 hours a week, and am a full time college student. I put eating at the very "end of my list." However, I hate looking in the mirror because I think I look skinny, pale, and not healthy. I want to just suddenly gain about 20 pounds, and if there were an easy way to do it, I would! Give me the fat injections, or something. That would be easier than having to take time to eat. The other thing is, after 30 years of not eating well, I get full after just a few bites of anything. I don't think I have anorexia, because I think I'm too skinny, not fat! But my friends think that it's strange to avoid eating. I also have braces on right now, so I won't eat in public. I want to know, do I have anorexia? Or is there some other disorder I might have? Are there supplements out there that actually increase appetite or make you gain weight fast? I think I'll try to get into a nutrition class next term, to see if that helps, but any advice or information would be really appreciated. I know it's time to do something about this...I just don't know where to start. Also, I might add that I have 2 different kinds of heart problems, and had a friend recently die. This really woke me up about my overall health. I don't want to be unhealthy. Tweet
