Feeling left out at work. But am I overthinking here?

[catchief]

As the title says. I'm feeling a bit left out at work but I don't know if I'm overthinking here or not.

Myself and a coworker (we're both the same age), we work one day a week at another office (same role, just split time). My coworker is a little higher than me, but we're usually still treated equally as we are the same age and did start almost the same time. Granted she's very much the bubbly one, the chatty one and generally gets on with everyone. I'm friendly and chatty but keep to myself a little more.

When we're at that office, my coworker is very much in the loop with what goes on in our main office. She gets calls from everyone, especially our session manager. He isn't her manager though, he's mine. And yet he never calls me regarding work or "a check in". It hurts my feelings sitting beside her at this job, knowing these people think to check in on her but never me. They know I'm there too.
Last week I had to go to the doctors for some tests and it was on the day we're in this other office. And I thought I'd get a call or text asking how I got on, how I'm feeling.. but I got nothing. Even on the days after. Yet, I know if it was this coworker they would have checked in.
I don't generally feel unwelcome in the office but it very much feels "out of sight out of mind" and when I'm not there they don't miss me but they miss her. Again, it hurts knowing they know I'm there too but never get a call from them.

Am I right to feel hurt or am I reading into this too much?

Sounds like you need to stop giving a shit what people say and specifically what you think they thick.
maybe this other person has made it so that those who call her etc felt they have to so she doesn’t burden them with crap.
you will never know how this person is seen by others so why waste time and energy worrying

I would never expect managers or coworkers to ask how a medical appointment went. In fact the one line manager that did do that was highly unprofessional and breached confidentiality.

I wouldn't have asked about your tests because it's an intrusive question. Wouldn't mean I don't care or wouldn't listen if you wanted to discuss it.

Same as pp I wouldn’t ask how a hospital appointment went because I’d worry it’s private/too intrusive to bring up.

Although, I can relate to being the less popular one at work. In my case, all stakeholders know my team mates name (started same time) but can’t always seem to remember mine.
We share the same responsibilities but they’ll mainly thank her and won’t always acknowledge my efforts. People aren’t rude to me and I get on fine with them, but I’m just not as loud and bubbly as my colleague so I’m not the forefront of people’s minds. 🤷‍♀️

Agree with the last two answers.
someone asking me about a medical appt would really be crossing a line.

Have you other examples as I am struggling to picture what the issue is.
