I’m starting to give up

Hello, I’m a 19 year old female & honestly I’m feeling huge. Like it’s the fact that I know I’ve put on some weight is making me very upset. Before I even say anything else, I few people who see me are like STOPP you are beautiful and you aren’t even that big. But it’s the matter that I no longer feel comfortable in my own skin because I’m getting anxious and paranoid that if I keep on this path of gaining all these pounds I will come off in the future with health problems. Even now I feel like some are developing and it’s devastating. I’m at my breaking point, I just need some advice... something. I used to be around 140/150 and now I’m 198 skimming 200 😭
