It’s my first day and I need help.

I’m a freshman, just started my first day of school. I’ve always been fat but have had family issues ands it’s gotten worse. I’ve always known I was ugly as well, but today one kid was talking to his friend and glanced at me as I sat down he burst out laughing and said “wow! She is ugly!” All his friends laughed and I broke out in a nervous sweat. It’s not the first time I’ve heard this nor will it be the last but I felt terrible, it’s never hurt me like this. I should mention I have a fear of people so great I have an IEP for it. I don’t want to sound like I’m whining but I haven’t had friends since sixth grade and my life sucks. I’m alone and I don’t know what to do. Any suggestions? [edit was for typos fyi]
