The new me

I can't seem to lose weight. I eat less then before. And when i go out i never finish my plate. I have stomach problems and mental block. Begining of last year i couldn't keep food down. I was throwing up everyday. So when my stomach is sour and tums and my purple pills don't work. I eat pretzels to settle my tummy. Or bread something doughy. It works. For a little bit and then i got to do it again. If i eat other times of the day i will still throw up my food or get close to. I am scared all the time when i eat. I am frustrated cause i can't lose weight. I really do try. Plus the gym is killing me right now. Which is good. right? My skin is also starting to bug me.
