So I am just a teenage girl but I'm not really that dramatic, I am a pretty 'whatever' person. I have this online group of friends from another city, I was once with them a few years ago but then I moved pretty far away but we still talk and I'm glad because they're my best friends. But recently they started discussing matters like when are they going to meet up for a movie or something and I felt pretty left out at the beginning since I'm not with them but I shrugged it off. They also go to the same school so most of the times I have no clue what they're talking about since it's basically just matters regarding their school. Then another situation happened very recently when I started doing a lot of jokes and those jokes were specifically mine. They were random and stupid and my friends often joked that they 'hate me' because of their simplicity and stupidity but I felt really satisfied because I can also stick out of this group with those jokes - since everyone already had specific personality traits it felt good for me to stand out as well. But then they started using my jokes and my way of speaking and I started to feel pretty bothered. I dropped a hint, asking them as a joke 'why are you copying me' but they responded back as a joke, still in my style of speaking. This and the fact that I live pretty far away and I don't understand most of their conversations make me feel pretty shit because I feel like I became the boring person of the group, now that I have neither personality traits that stand out anymore or any idea of what their subjects are about. I'm a pretty lighthearted person and I usually hate when people take things to seriously so as much as I want to tell them that I feel that I'm just going to be considered as overly dramatic and too childish or maybe they'd think that I can't take jokes.
I don't have friends in my city so they're my only option as well and I feel really lame and just stupid for getting upset over such things but I just wanted to vent for a bit and I didn't have any other place where they wouldn't see it aside from this one.
I'm really not used to speaking with strangers about emotional matters like in this case but everything has a start I guess.

Hey, I sincerely feel sorry for you. I do not like to talk about my feelings, I hide everything and myself, so I understand you. I am not a rare psychologist and I do not know very much about such matters, but I think that you should talk to them honestly or slowly break the contact and try to find friends in your city :) I wish you luck :)

and do not worry, people change so it's difficult to get along with them at some point, that's how it is ...

I think that when you talk to them honestly you will know if it is worth fighting for your friendship or not
