Why do some people NEVER gain weight and I do?

It's so unfair. My friends eat so much and NEVER gain weight but if I have to eat one piece of cake, I will definitely gain weight. The other day I had 2 slices of pizza and my best friend had a whole box of pizza and she is soOo skinny and I'm not!! I don't eat bread, rice, cereals, sugar, none of that and I go to the gym 3 times a week, not because I want to but because I have to, to keep my weight down😔 Lately I've been so busy so for a month I couldn't go to gym and I gained 5kg, that's more than 10 lbs if I'm correct. My friends don't go to gym and they stay being skinny. Why is life so unfair😭😭😭
