I started a new job around 6 months ago, we go into the office 1-2 times per week. I avoid it as much as possible.
I'm quite introverted and I realised I have been isolating myself from everyone and being quite antisocial and I don't really know why or how to shake out of it. We don't have assigned seats in our open plan office and I deliberately book a seat in the corner or deliberately wait for there to be no seats left so I have to book a random seat surrounded by colleagues I don't know rather than sit with my team).
At lunch I often make an excuse of an errand I have to run and then take my time to avoid meeting up with them afterwards.
I also avoid after-work drinks/meals out as much as possible.
I hate it about myself. I don't realise I'm doing it until I catch myself scoffing an M&S sandwich on a bench in freezing cold windy weather rather than join my colleagues in the work cafe.
My colleagues are lovely and tend to message me to invite me to join them but I think that they will obviously lose patience eventually and give up.
I also get hurt seeing other friendships blossom whilst I feel quite lonely and isolated. I always come home feeling so dejected.
Does anyone have any advice?
I should add I wasn't like this in a previous job. I'd happily sit with colleagues and was quite outgoing with them.
