What should I do?!!

Tell your friends when you aren't busy so they know for sure. You don't have to get rid of this friends group in order to have more friends. If your current friends aren't really treating you like a friends find new friends. There are plenty of good people out there that are in a similar place as you.

Tell them that you arent busy and if you hear them talking about something, join in the conversation.

That's a good idea and also, invite them yourself. Let yourself be heard :)

I try to tell them that about a year ago and when I asked them if I could come they said they didn't have enough tickets or that there was already to many people... I will try it again tho but I'm not sure how well it will work.. Thanks for the advice tho.

If invite them they say they are busy tho :/

Thanks ill try that!!

You should tell them how you feel. Tell them that you feel left out and try to plan things ahead of time if at all possible. After you let them know how you are feeling and things don't change there is nothing wrong with a new inner circle of friends. You don't completely cut ties with them but find other people that will hang out with you. I am sure you have other friends around but you may not be as close to them as you are the people that are leaving you out now but that can change. Your not "stuck" with these people. all it takes is asking a question which does take a lot of guts.

I actually went through something similar. I had the same group of friends since elementary school and during high school they all started doing their thing with out me. We just became too different of people. I just left the group. There was no hostility involved, we just moved on. In doing this, I found the greatest best friend I could ask for (still friends 8 years later) and met a few new friends in college.Point being - no I'm not the most popular person anymore. My phone isn't always blowing up, but I have a few GREAT friends that would do anything for me. To me, thats better than having more friends who don't care at all.

Thanks for the advice!! :)
