13 and 139lbs

So I’m 13 almost 14 and 139lbs, I’m 5’6. I feel like I should lose weight but I honestly don’t know how to quickly and plus I’m lazy(🤷🏻‍♀️). Should I lose weight or am I fine?? I see myself as absolutely huge and I don’t eat most the day because I’m scared of being bloated and looking bigger is not eating just making me fatter?
