I have worked for a large company for 30+ years and have always done a good job and got on with my colleagues. I recently moved to another department to broaden my horizons and am beginning to feel I've made a mistake 
Everyone in the team is around half my age and it is a whole different culture from my previous team. It seems like being back at school as there is so much chatting, mucking about, swearing, using phones etc. I think they feel that I am just a slow old woman and some of them seem to be picking up on the slightest thing I do wrong. I have also overheard a couple moaning about me as I stood behind them but felt too scared to say anything at the time as I feel so anxious at the moment.
I have been in tears some nights when I get home. It feels like some subtle bullying may be going on but I'm not sure if that's me being paranoid or not. I just get the impression they were rather I was rather not there.
Has anyone else been in this situation at all? Does it get better? Any advice would be helpful.
