Yeouch, that is awfully relatable. For reference, I’m autistic but stuff like this can easily intersect with a lot of different things or suggest a mixture of illnesses/conditions. As PaX and Vaggumon have mentioned, your case seems to have hints (??? like food like hints of lemon, idk how to phrase) of what someone with ADHD or social anxiety would experience, it helps if you examine what the source of your behavioural patterns could be.

In the case of my autism, I have an aversion to socializing at times because I have issues of expressing myself in a comprehensible way and get tired of trying at times. I can’t understand phone calls due to processing issues, too. Differs from autist to autist though, so ymmv (hope this is the right phrase).

In the case of social anxiety, your behaviour would likely have an aspect of fearing judgement to it, fear of messing up, like being afraid of using the wrong words or sounding weird when calling.

I don’t know about ADHD but I imagine executive dyfunction plays a role in this? As in, you feel compelled to do a thing but your brain can’t seem to divert its focus to actually do the task

So, in short, depends on how your behaviour came to be (sorry if this isn’t helpful)

Edit: I took a bit of time writing this, and others have added onto this, mentioning avoidance coping and avoidant anxiety. Evidently, there are a lot of groups of origins/reasons (???) for certain behaviours, ranging form defense mechanisms to certain brain wirings, whether you’re born with them or have adapted them later. Definitely seek out a professional if you can!!!
