Why is everyone my age bigger

I just don’t get it I’m so skinny but a lot of you guys tell me not to put on fat with the muscle. Everyone else has more fat than me I look sickly. They obviously don’t all have more muscle than me so what is wrong with putting on fat when it is needed? Sick to death of being this thin, summer is coming and I won’t be able to hide it and it’s stressing me out! I don’t even fit my clothes I look annorexic unless I layer why am I like this
