Food issues😂😂

So I'm only sixteen and ofc I have self image issues but now more than ever. I was bullied a lot when I was little so the littlest weight gain freaks me out... I weigh, last time I checked, 120lbs... I love food and I love to cook. I eat a lot of food all the time except during school ( I only eat a little sometimes not at all). But I've been gaining more weight than I'm ok with Bc I've ACTUALLY been eating more, trying to break my habit of not eating but now I'm starting to feel very self conscious but I feel like if I don't eat I'll make myself sick. I play soccer so I drink water but now I'm scared to even drink anything unless I eat something Bc I I don't eat I usually throw up. I don't know what to do pls help!?!?

This is current( ignore my messy room pls) I know I'm kinda skinny but I always end up comparing myself with other girls.....so yea idk what to do.
