Would you be friends with a fat person

So I have friends but there not really my friends because its more me thinking their my friends and me being a joke to them. So I’m fat and there all thin and there always leaving me out or whispering about me but loudly whispering where it’s so odvious everyone can hear what there saying. There always saying stuff aswell like ‘they enjoy being stood next to me because it makes them look better’ and before one of them complained about being fat and one of the others said well at least your not as fat as her aka meaning me. There is also that game they always play and I always say I don’t want to but include me anyway and it will Be questions like who do you think is the prettiest in our friendship group or who has the best figure and they always play because no one ever chooses me. Ive never had a lot of friends and I think it is because I’m fat. Would you not be friends with someone or treat them worse due to size? Just curious because it seems as long as I’m fat I’ll never be valued by other girls
