i feel so lonely

i feel so lonely and like i have nobody to talk to. I have friends but not real friends just like school friends, the people you only talk to in that one class and don’t outside of it . I used to have closer friends but we all kinda just drifted away from each other and they only talk to me when it’s convenient for them.. I haven’t been out with friends since like last summer which was 7 months ago .. nobody invites me to anything and it makes me feel like shit when i see them posting stuff on social media having fun while i’m in my bed .. in the dark .. all day .. i’m 16 years old .. i should be out on friday night’s having fun and making memories. I haven’t done one thing this school year no homecoming, no football games , no school event and parties. I feel like i’m just wasting my youth and all my time is being wasted and then when i get older i’ll have no crazy stories to tell .. my life seems so meaningless. if i was to leave this world nobody would care i’m not suicidal or anything i just feel like i haven’t affected anyone enough to care , they’d get over it in like a week max. i just want real genuine friends but my social skills are terrible and i just feel like nobody likes me. people always tell me i’m boring and i feel like i have no personality at all and to top it all off i have 0 self confidence. i hate feeling like such a loser .
