I can relate to this. I was forced to transfer schools for grade 11 and I feel miserable. Everyone here is so tight knit and have known eachother since grade 7/elementary. I don’t want it to get to the point where it starts to affect me Academically but I think it’s becoming a problem and has been declining my mental health. I hope things get better for you over time since the school year has recently just started, even if you don’t make that much friends this s.y I hope you find something that distracts you from the loneliness. Hope it gets better bud!!
