M.P.
I just commented on your next post. These two posts sound like they are written by two different people. I am retired from a predominately male profession. Men do generally think differently than women. Your team members are in a different time in their lives than you. Of course they don't understand you. They do value different things because they are vastly different than you. They do value good work and are successfully working as a team. Then you join the team. You do not fit. I suggest you won't be able to adjust to this work environment because you are very different than other team members. This is not a good fit! I wish you'd edited this question instead of taking an entirely different approach.
I believe that you can learn while working with this team. Your time there is limited. Sounds like you are internalizing the differences, taking them personally. Know that you are OK even tho you're different. Remind yourself you're learning. Focus on what you can do. Expect to not be accepted. Use humor whenever possible. Flatter them with the humour. Said in a lighthearted way, "of course you can do more! I'll just plug along beside you."
They are friends and talk about more personal things. Just listen or not. Because they do not understand about husband's and babies, talk only about things to which they can relate.
Do not try to defend yourself. They don't understand. When you come across in a defensive manner they will be critical. They know you can't keep up so agree with them. Don't apologize. Just do the best you can do. Act confident until you feel confident. "Fake it 'til you make it." And don't complain to management because that will cause more bad feelings by the team.
If you can approach management to ask what you can do to improve your work, that might help. Go no further if management says you're doing OK. It may be appropriate to mention you don't seem to fit in and ask how you can work better with the team. Don't say anything that implies criticism of the men. It really doesn't matter they are young, unmarried, different than you. Use intellectual words. Don't mention anything personal related to your personal life. Leave emotion out of the conversation. Focus on the work product.
I also suggest you talk with a work related counselor. Consider that there may be a different way to use your work knowledge and skills.
I was able to adjust to my work situation by having counseling. The counselor was an older man and able to help me understand the men and how they think.
