Am I the only one who feels friendless and lonely in high school

Hi, Im a high school student in my junior year. As all of us know already, the pandemic happened. This caused everyone in my grade at the time (whom were freshmen) to stay quarantined. We stayed quarantined till junior year. I have a total of two friends in my grade because of it that consistently talk to me still and a sophomore friend i met during my first days back. Sadly, none of us share the same classes so im basically friendless and alone during school time. mostly because no one would come up to me and talk to me ; I tried in my art class this one time and the guy basically buzzed me off. Its sad, everyone around me makes friends easily however when it comes to me no one wants to talk to me. It gets lonely and sometimes i cry by myself in my room about it. Its hard knowing I wouldnt have anyone to sign my yearbook during senior year. Idk i feel like if the pandemic never happened i would have had much more friends, learned more and focused on my education, became happier etc ( many people could feel the same way tho). I feel like a pathetic loser sometimes, seeing people go places with their friends. going to partys, the movies, parks while im at home watching it on their IG stories. I dont want to come off as a weirdo complaining about high school shit but i have no motivation to go anymore. That and alot of the freedoms my school use to have got taken away because of the childish freshmen but thats a whole different story.
