When you feel yourself getting replaced..

Sorry I really just need to get this out of my system.
To start, I'm not a very social person. I really only have one good friend and that's it. I just never had any good friends in my life before, I was either ditched for someone else or they just decided I wasn't good enough- who knows. And I'm the type of person that needs someone to be around and trust- I'm extremely clingy and I'm not gonna deny it. Even though I'd prefer to not deal with people, I need someone to be there for me and help me and just listen to me when I need to rant or be my shoulder to cry on when I'm sad. And I thought I finally found someone that wouldn't ditch me last year. We were ok friends last year, and continued to talk over the summer (which I had never done before) and eventually I considered her my best friend, we went on the band trip together and we either text each other or talk in person everyday. She is wayyy more popular than I am- and not only does she have another best friend but she also has a girlfriend. So even if I wasn't there she's still have.. Someone. This past week she went on a school trip out of state with a few other kids and apparently is now friends with the girl she and I used to hate with a passion. The same girl that tried to steal her from me last year. And they have new nicknames for each other and judging by the pictures she sent me they obviously had a great time. Maybe I'm just being jealous and clingy but I just.. I don't want to be replaced- this is the longest friendship I've kept without getting ditched and at this point I'm wondering if friends are even worth it. Maybe I'm just blowing things out of proportion but my brain keeps telling me how I'm being replaced and that she was never my friend and that I messed up our friendship and everything and that I was too clingy and that she's happy that she could finally get rid of me and I just need some reassurance.

Been there. Instead of freaking out and talking yourself out of your friendship you should try to do things to build your friendship. See if she wants to hang out - maybe become more friendly with her girlfriend and her best friend? Instead of focusing on her relationship with this other girl - focus on your relationship with her. Strengthen it :)

100% agree with Ruki
I am in somewhat the same situation as you (drama - ugh) and I don't pay any attention to the other girl at all (we have had a horrible past and she can no longer stand me blah blah blah), focus on YOUR friendship. Spend time with her and try to maintain your friendship, things do change - it'll work itself out, everything usually does. But you have to be a part of it and act. Nothing will happen if you don't do anything.

I do hope I am making sense, I'm horrible at explaining.
I guess what I'm saying is don't give up on the friendship, trust in it - everything happens for a reason.
You'll get through it, life continues - and all's well that ends well, right?

If you ever need to rant I've got two ears (or eyes to read) to listen, and I can try to help you through whatever you need me to listen to.

I hope I did help.
Yours truly.
