I have a manager title but in the sector that only indicates that you aren't a new graduate. I am nice likely too nice and joined a team almost three years ago where my then wonderful line manager would complain about how quiet and unfriendly the other team members were. To get around this I would make conversation, sometimes no-one else would join in on the weekly social chats we are encouraged to attend. They would sit on Teams muted. Even years later they are standoffish and rude to me. I don’t expect to be friends but they make rude jabs when I speak about my children but won't offer any other conversation. A colleague I assisted when she was put on a performance improvement plan was making rude jokes at my expense.
I feel awkward with the silence and so I tried to fill it it but I feel it has backfired on me. It doesn't help that another colleague believes they should have a manager role so keeps pointing out any and every mistake she finds across the team.
It is not a great team and someone has just left after three weeks but I think this is a common fault with me. Even when I started the role they were so unbelievably rude to me and having just come back from maternity leave to a new team I didn't really know what to do. I struggle with anxiety and depression and work is starting to show up in my nightmares. I'm also not assertive in any part of my life. I get very sweaty and my heart starts to beat very quickly if I have to speak publicly or challenge anything so I go to humour to feel a bit more comfortable. But I'm tired of feeling like a mug. I'm in my early 30s and I feel 12. Are there any books, resources etc that anyone could recommend?
