Third wheel 😟

A lot of times when I hang out with my friends I feel like a third wheel...My friend had her bf over and she started making out with him while I hid in a corner. It sucks ive had one gf and her mom is homophobic so she broke us up and the two guys ive been with have called me fat and told me to kill myself. A lot of times I feel hopeles and like no one will ever want to date me. I love cats so like..If you guys have cats can you maybe share them
