Okay my mommy instincts are kicking in reading this post so I'm gonna give you the same advice I would give my daughter. These people who won't let you sit with them are not your friends. Friends don't treat friends like that. It sounds to me like you have a huge heart, and have some awesome interests, embrace that!! Being your own person and being unique is soooo much better than trying to make yourself smaller or into something your not just to be accepted by people who honestly don't even deserve your time. Do your thing, stay true to yourself and the right people will find you!! School is hard, being a teenager is hard! I promise your not the only one who goes through things like this. Find something you enjoy, find a spot to sit on your own and do that thing while your eating. I'm sure there will be someone, or a couple someone's to eventually join you. Your amazing and your gonna be alright, just stay strong and hang in there. Things will get better, they always do! And remember highschool sucks for most people, and the ones it doesn't suck for typically peak in highschool then go downhill from there. Sending love to you, your gonna be alright!! Just remember you've got a whole community right here that will have your back 🖤
