i feel lonely

and there's nothing i can do about it, i feel jealous looking at big friend groups, i have a few friends and also i was a part of a friend group, but i always felt left out, we once planned on going somewhere but i declined because i wasn't interested and they all started making their own assumptions and said that i actually had plans with some guy and started teasing and shipping me with that guy, so i kinda got offended which i didn't show,some of them even said i was acting up. they all were the friends whom i considered close, so i left the gc, and no one bothered to apologise and a friend of mine whom i considered the closest, i contacted her and she apologized later when i apologized for getting offended, her apology didn't even seem genuine and now no one really talks to me much. i feel like, i wasn't even needed in that group anyway. tomorrow's my 16th b'day, again, another year, celebrating birthday alone, happy b'day to me 🎂
