Hey guys, just wondering… Because, well I’m in 8th grade and I feel like next year is going to be a fresh start. I moved to the U.S in 7th grade, and well I haven’t really found a group of friends or a best friend here 
People for some reason don’t like me, maybe because one time I tried to copy this popular kid at my school and started talking to a lot of girls, but I stopped about a few months ago because I figured that being myself is better and studying is so much better than popularity, I even deleted my Instagram. (Kept my snapchat in case I wanna talk to or ask some people at my school), but I only went to a friend’s house in these 2 years. I feel lonely but I think that high school is a fresh start to make new friends at my EC’s and classes, is this true? When did you find your group of friends/best friend?
I found most of my friends through band. Any EC to which you can dedicate a lot of time will provide ample opportunities to befriend other participants.
I found most of my friends in eighth grade, but our group definitely expanded a lot in 9th and 10th grade. You’ll be fine–don’t worry.
Yeah! I walked into my first period class (PE) knowing NO ONE. But the person next to me struck up a conversation, and even though I’m not very close to her anymore, I’m glad, because that conversation was the catalyst to a lot of great friendships.
ECs, like @bodangles said, are a good way to meet people. Even if you’re shy or timid around others you don’t know, you’ll find your group 
Or even just one person! High school is a fresh start, as you said.
Don’t worry about it, just put yourself out there! Do a bunch of clubs and sports and be active! I did track, cheer, and cross country and because of this my team feels like a family. Be nice to everyone and treat them well and you’ll have lots of new friendships
Also, don’t be afraid to just say “hi” or complain about something you both don’t like (i.e…“I hate waking up so early”.) I met my best friend by just saying “I like your shirt where did you get it?” Just normal, casual things. Compliments work very well
IMO ECs are the best way to make friends, because everyone who’s in the EC will, for the most part, have an interest that you share.
I met my main friend group through marching band. Where would I be without them? No one knows
I was just like you moving from a different school to middle school and it was tough but in high school everyone is very positive at least in my schools and if you are very talented at something people will respect you for that. Also be very open minded to some one elses comment and talked to them I just made a ton of friends. Clubs, Sports, and classes with lot of people are a good way to make friends
