Skinny probs

I just want to complain and even cry. I'm a very underweight person. 97 pounds, 5'7, and am 19. All my life had it rough for being really thin.... So many names, things being said under people's breaths, clothes not looking/fitting the best and always worried I'm going to lose weight and be even skinnier. It's so hard.... Especially when you have no boobs, thighs, or a big butt 😂 and that's all guys like, barely anyone accepts thin people these days and it's really not fair. I used to eat a lot but now this past year my appetite has been so weak I been to doctors they won't do ANYTHING to help me. I need a appetite booster ya know so I can just eat eat eat than maybe I can get a couple pounds  but no one will help me. I need/want the weight. Having a super high metabolism and a weak appetite "now" it's even worst. I was 105... Anyways idk what to do, anyone with any ideas please comment and suggest id appreciate. ☹️
