Why don't my friends wanna hang out with me?

Hey guys I really need some advice. Okay so here is my story starting from grad 8. When I entered grad 8 I had a hand full of friends. I was not the popular guy but I was no loner. But I had one problem. I skipped school everyday. I was barley at school. But I still hanged out with my friends and they still made up stories to my teachers when they asked them where am I. So I am grateful for that. Anyways I skipped school until I was in grad 10 and during grad 10 my vice principle had enough and told me to go to this special school so I can catch up on all the work I missed and he said I can come back for grad 12 which is grad year. So I agreed and I went to this school not telling my friends I just sorta left without telling anyone except my family. So I went to this school for 2 years and got lots of work done. But during those 2 years I never once hanged out with my friends I just told them what happen and talked to them on facebook time to time. I have an older brother and sister and they both always go out and hang out with their friends. So I thought I'll just message all of my friends on facebook asking them if they want to hang out. All of them always made up excuses. And for 2 years it was like this. The only time I went out is when my brother went and hanged out with his friends because my friends for some reason did not want to hang out with me. And my sister, mom, and dad always say "You have no friends so you go and hang out with your brothers friends" I just ignore them but in the inside it hurts me because I really feel like I have no friends. I'm 17 and my brother and his friends are 20. They like me though because they say I'm funny and they feel like they can do anything when I am around them becasue I am younger what ever that means. They always ask my older brother when he goes out and I stay home doing nothing other then browsing t.v. channels for 2 hours "Dude wheres your brother? (me) Hes MIA (Missing Out In Action). So they like me but I still feel like I'm not wanted by them becasue they are probable thinking "Doesn't this kid have his own friends as well." It really hurts me because I make up fake stories to my brother and his friends. Like I would say things like "Hey guys my friends are planning a party but I don't wanna go." I'm returning to my old school this coming school year and I am the only one out of my so called friends that can drive and I think they will only hang out with me becasue I have a car and I am willing to except that becasue I can then say "Yes I do have friends and we hang out all the time." Just the other day I asked my old friend from grad 8, 9, and 10 for his number so I can text him and we can plan a hang out he said to me "Sorry bro I got no cell." Then one day this girl that I know asked him the very same question the next day and he pulled out his phone and gave her the number. I still see some of my old friends walking down the street and they see me sometimes hanging out with my brothers friend and they just wave and keep walking and I have not hanged out with them for 2 years. So can you guys please give me so advice on how I can start hanging out with my friends or do they really not want me and I need new friends? And why don't they wanna hang out with me? Thanks in advance. Oh yeah its gotten to the point that they wont even reply to my facebook messages.
