I think I need help..

I've been having a lot of health issues recently. The more sever they get the more I'm forced to come to this conclusion.... I think I'm anorexic. I always had this feeling, or thought that I'm not sick enough to be anorexic. I'm not thin enough to be anorexic. It's not that bad. Something else is wrong..

Now on to the health issues. Over the past few months my hair has started falling out and my once thick hair is very thin. I try very hard to cover the balding spots and style my hair so people can't notice. I'm constantly exhausted. I can hardly keep my eyes open, even when driving. Hot flashes like crazy and then im freezing the next minute. I go days without eating or only eating something small for dinner like a peanut butter sandwich. Not that I'm trying to drop weight on purpose but I always feel like there are more important things I could be doing. I can always eat later. When I do eat it's in such small portions because I get so full so fast and feel sick. I take a lot of vitamins to try and get everything my body needs but I don't think it's enough anymore. Ive lost 10 lbs in the last month. 40 since January which leaves me at 5'2 and 120lbs. I know I'm not fat but I can't help but find all these flaws when I look in the mirror.

My husband makes comments about not eatting enough. Mostly that my hair is falling out because I'm vegetarian. I'm so lost right now. I don't know what to do. I'm filled with anxiety and want to disappear.
