I feel like I don't belong in my friend group
I am sorry that you are experiencing friend troubles! It sometimes feels like the end of the world in school, but it definitely is not!
Is there a reason you cut your friend off? Did they do something to hurt you? Do you just not vibe with them?
When you felt hurt in class, think of how hurt your other friend must have felt when you blocked them on everything with no explanation. In my opinion, I think it is important to give them a reason why, if you can find one - unless they know what they did. Would you be open to talk with this friend?
Maybe your "best friend" feels a bit on edge and that you might block them for no reason. I think honesty is the best policy. Talk to your friend and ask them what is going on.
I am here if you need to talk.
All the best,
It seems a bit of a puzzle. If I understand you correctly -please do set me straight if I've made a mistake - for a year or so you had two good friends then you break off with one, not just by letting things slowly fade, but a pretty abrupt change.
Although that friend tried to restore matters you remained firm, but now find your other freind is maybe a little more distant.
Sometimes I do not know why I might do something until later on, so can sympathise with you when you say you don't know why you did this.
I guess until you do get an idea of why this happened it is going to be difficult. As Jaz has said there might be several reasons,
You do say at the start that you don't feel like you belong in your friend group, and a little later on that you are not appreciated, do you think this might have had something to do with it?
Has there been anything in particular in the past that made you feel not appreciated?
I know you are finding it difficult to find the reason, and although I could make suggestions I'd imagine you'd prefer to think on it for a while.
The only obvious thing to say is what Jaz has already mentioned, your existing friend might feel at sea and not know what is likely to happen to her.
If you can manage it and follow Jaz's suggestion and talk it may well help. Sometimes another close person's view can give you an idea that seems correct. Plus when people understand they are much more likley to make allowances.
What do you think?
