Can Any One Help Me With This Please?

I'm really subconscious about my weight, even though I know I'm not fat or overweight, I still worry a lot. My best friends say I'm the skinniest out of them and they say I'm like anorexic, but truly I'm not. My friends also say I'm stick thin and my family says that too, but I don't think I'm all that skinny! I'm about 4'10 or 4'11 and I'm 76-80 pounds, it varies. But I don't wanna become anorexic or anything and that's why I'm worried. I want to lose about 4 or 5 pounds because I'm shorter and I don't think I'm at a good weight, even though everyone says I'm stupid for thinking I need to lose weight. I don't like feeling full, I don't like breathing in because it poofs up my stomach, and sometimes I don't eat things some days because I hate feeling full! I always have something to eat in a day but sometimes I just don't eat a lot. I don't want to tell any of my close friends or family about this because I don't want to go to a shrink or anything and they'll just laugh in my face and think I'm acting up. Any one have any advice for me or can share their experiences with me? Please help me because I really want to lose weight but I don't want to endanger my health or anything.
