Peaceman,
It's nice to hear from you. I have been wondering how things have been going with you and your new baby. Sorry to hear that you're having a hard time at work.
I can relate to what you are saying about the younger rowdy co-workers. I went back to school last year and the average age in college is much younger than me. At 38, I am old enough to be a parent to some of these other students. It is really easy for me to slip into being irritated or threatened by them. If I feel myself going down that road I just remind myself that I was pretty self absorbed and rude at that age. They are just being young, full of energy and maybe not a lot of tact. It's not about you, and even if they are saying something about you behind your back, it's really just about them and their limited view of the world. I smile and remember how clueless I was in many ways at that age. I'm choosing to be amused rather than threatened. They are probably feeling unsure too, just like you and me.
The only way I know to get over this social anxiety is to push myself into uncomfortable situations, and gain strength from making it through. Being in college has been a really hard challenge for me, some days I just come home and cry, it is so hard some days. Then other days I come home feeling victorious because I have felt pretty comfortable in what was a couple of years ago, too much for me to cope with. I make myself talk to strangers. If you talked to a new person every week, or talked to at least one co-worker a day, or whatever you could manage, you would be feeling better soon. I know this is hard, but the more you do it, the easier it gets. In school, I make myself speak up in class. Sometimes my voice shakes, but I keep talking. Sometimes I blush and my throat feels tight and like it's closing up, but I keep going. People are going to look at me and know that I am uncomfortable, because I am, and that's OK. I can't hide how I feel, I just have to work through it. It's really hard sometimes, but you can do it!! You will feel so proud of yourself if you start to challenge your current behavior.
The up side to being in college is that most other things now seem easy. There isn't anything much that is as challenging to me as being in a classroom with lots of other people and being expected to participate in discussions etc. Things that used to really bother me now seem like no big deal in comparison. Doing things that are hard really is the way out of this. Believe me, I spent enough time waiting patiently for a miracle, this works much better.
I am here most days, so if you ever need help, I am here for you. Please remember that you are not alone in this.
Your life can get better.
