Need advice about talking to some old friends please help.?

So back in fifth sixth and seventh grade, I was one of those people everyone liked. I was in football( not bad but not great). I had alot of girlfriends ( i know it seems like young for that but our middleschool is like high scool). I made mostly A's and got into a few special cles and had oppurtunities such as taking the ACT in seventh grade which I did. I was never mean to unpopular people and tried as much as could to be nice to everyone and never bullied anyone. I always tried to be the nice person who was only mean to mean people who truely deserved it such as an *** who picked on an emo girl and retarded person, who I wasnt nice too because he was a . I dated like 30 or more girls in that time period haha. I was friends with the most popular people in school and hung out with them alot the most popular girl in school was one of my best friends I dated the hottest girl in school along with alot of others and most all of the "cool" girls there were about 6 of them that were "coolest" idk how but it just seemed that way and everyone called them "cool". Most of the cool guys came over to my house and went to do stuff with me alot at least most of them like 6 of them. They were not all "jocks" one was in no sports and a few in only one. Then, in seventh grade, a new kid came to school who I was nice to because i always try to make new people feel accepted in our school we became good friends and i hung out with him and my "popular" friends alot. He soon became "popular" but I realized he also became an *** and picked on people I never seriously called him out on it because i didn't want to make things awkward between us. Then, towards the end of the year, someone spread a joke rumor which I won't bother repeating on here about me going to like attck him whe he came over to my house one weekend. He never came over that weekend and first hour on monday, I just got to school, came into my homeroom and sat down. Everyone was running up to me asking if I was going to fight him or not and I still didnt even know the rumor which WAS complete bs some jerk must have said as a joke. He came in my cl ran up and punched me in the side of my head as I was sitting down looking at a friend to ask them what was going on in my desk. I got up after he hit me again like four times over and over and still hadnt quite registered what was going on. I got tired of being struck in the face after the seventh hit so I swung back as hard as possible and hit him in the eye and he started flailing his arms around hitting me as much as he could with little aiming like just flailing aroun hitting my head. I pounched him really hard in the face a few times purely out of self defense, a crowd of like 45 people sat in my room and watched in silence as we fought around the room. Finally, I doged a few punches and was getting ready to get serious like as in punching him in the throat or kicking out his leg when a teacher finally broke it up. I didnt want to hurt him it was purely self defense. He got suspended for the rest of the year but I came back the next day being innocent. Everyone made a huge deal out of it saying i beat the crap out of him or he did to me (about 50 50 on who won I didnt care i just wanted them to forget) and I just dismissed them. Idk how exactly but over that summer, I only hung out with my less popular friends a couple times and did nothing else. I didnt contact my popular friends and they didnt contact me not like a hate thing we just didn't hang out. The next year it continued and I talked to them very little and made a few new less popular friends. I talk to a few of them a little bit still but thats it. I am now a freshman in highschool (oh yes, the kid I got in a fight with and I havent spoken a word to eachother since and have been in alot of the same cles) My grades have dropped to B's and A-'s one C+ but that is awful for me cause i wnat to go to lawschool. I am in no sports at all just speexch and debate and let myself go pretty bad physically. In 8th grade halfway through the year was my last girlfriend we broke up a month or to later. I need to know what to do to get my old friends back I am getting really bored depressed and lonely. I am now not like fat but pretty overweight which I am really selfconsious of. I want to hang out with them. so far this year, I have had one person come over about ten times who is not popular but not unpopular. I want some of my old guy friends back and want to know what to do to hang out with them again and when I work out occasionally It only lasts a few weeks untill I quit from no results. What should I do? this is really serious for me and not about being popular they were my good friends and we had alot in common. Please list what I should do to get them back I need people to hang out with please help even if you dont know tell me anything ill give best answer trust me
