I lost my best friends?

I've lost my my group of 5 best friends.we were always together at school and for almost 3 weeks now none of them have talked to me and a lot has happened in between this period of 3 weeks and now( they even told people iwas trash talking about them-lie)there is a long story behind why we no longer talk but I think I will just say that it seems as if there is no longer hope for our friendship .

It started when they misinterpreted something I said and They said I was being a bad friend.they were really good friends but i cant fully forgive them or go back.whenever I see them a small part of my heart cracks.i feel alone . for the first week I had no one to talk to and felt like I was constantly following other people around.what have I done? sometimes tears just run down my face. I never want to talk about it.i always feel like being alone.

Yet something inside me gives me hope grand be happy instead of being sad all the time.i try to make new friends.even though they can't ever be replaced I try to smile and laugh and enjoy myself even though it soon fades away.maybe this all happened for a reason.

I constantly feel lost.what should I do? this is really hard for me especially because I have self esteeem issues and my parents are in the midst of divorce and I feel like I don't have anyone.
