**** them all. Focus on urself as u ll grow and be more attractive and capable they ll automatically come to u from aall directions !
You could look at your behaviour and you could talk it through with someone. It maybe that they are not the right friends for you or you are at a different stage of development than they are. We all change quickly in our teenage years and at different rates in different ways. mx:))
give and take, maybe they're busy in their own life as well, if they come back you take them back all over, if not, go to the library, invest in knowledge or pick up some new hobbies crafting baking or exercising or programming.
Make new friends.
Do your own thing then. Move forward in life.
Find new and better friends - REAL friends do not drift away
