Hi Crewman
A few things came to mind as I read your post.
You have been on the job about a month. Your co-workers are nice. This tells me that they must like you or they would be more on the snobbish side after a month's time.
One thing about shy people. For the most part they are very good listeners. And by nature people LOVE to be around someone that will listen to them talk :wink: (This is a PLUS for you) This is why shy people make very good friends for someone to have. For friendship needs someone who will talk....as well as someone who will listen.
BUT........
You are feeling backwards.......like you don't quite know what to say. Sort of like you are on the outside looking in.
Perhaps a little role playing on your part might help you. Have you ever tried role reversal inside your own mind? By this, I mean, have you ever tried to talk to one of them and pretend that it's not YOU that is shy....but THEM! Pretend you are trying to draw them away from THEIR shyness by asking them questions and being very interested in their answers. I'm sure that over this past month there are things you sincerely would like to know about them.
One more thing......
When you were hired the person that hired you must have thought you would fit in with the crew. This is almost as important as your ability to do the job. Employers know that discord within the work environment is very unproductive. What I'm trying to say........is they saw something in you that they liked beyond your abilities to perform the job.
You seem very sweet.........something tells me that you will be just fine, once you learn to believe in yourself as much as others believe in you
