AIBU to think my friends are low key taking the mickey

[Mazzatron]

I'm in a WhatsApp group with two friends, we talk p much daily. It's a very supportive group but I've started thinking they are sometimes taking the mickey out of me, the way that I text / talk. I've noticed them using phrases / spellings they wouldn't usually use that I use, but it's kind of incongruent when they use them, usually when I'm explaining something. I don't know if I'm being completely mental / paranoid though. I don't know why I feel like this? They are lovely and supportive ultimately. I just have a sense something is a bit off. Unsure if I should say something but wtf would I say.
Has anyone else experienced low key belittling or mickey taking like this ? Is it a thing?

Give a few examples of the sort of thing you mean.

Honestly it sounds so petty but elongating words, and using expressions I use like "oh maaaaan" and "jeez" which they would not usually say. So it feels like they are saying it to make each other laugh behind my back ? They are v intelligent and eloquent, more so than me. There are a few other things but they actually look on here so I don't want to put everything down

It’s not uncommon for friends to mimic each other unconsciously. And in particular ‘jeez’ is fairly common vernacular, that a lot of people use.

I don’t know enough about your friends to form a judgment but I would try to give them the benefit of the doubt.

My friend calls everyone babes and l sometimes take the pee out of her for it but it is not in a nasty way - l love the fact she calls me that just not something l have ever done myself - maybe they see it as a nice thing

It’s really hard to judge without seeing the full context, but from what you’re saying it does sound plausible it’s mocking.

I think you may be being a little bit paranoid and sensitive. I use similar terms in some of my WhatsApp groups and I would never utter the words out loud - things such as 'thanks babe' etc. I don't think I've ever used the word babe other than to talk about the talking pig!!

I think you're being paranoid. I often accidentally pick up a phrase I heard somewhere else, and repeat it. It's probably that. Also those are very common words.

Ok kind of relieved (I think?!) to hear most think that I'm being over sensitive and paranoid and they might be doing it in a fond way, if they are even aware they are doing it at all. Thank you. Now the question is why am I like this?! (Rhetorical)

I'd be annoyed if someone parroted my writing style and would absolutely think they were taking the piss, especially as there's two of them.
