36 weeks and uncomfortable

I really enjoy being pregnant despite having gestational diabetes and having to watch what I eat. I haven't been too uncomfortable until this point. I'm a nurse and work 12 hour shifts on a very busy unit. My legs ache terribly tonight. I sat down for lunch and it was cut short. I have three friends who are also pregnant and are stay at home wives and do not work at all. They constantly complain and I just want to go off on them. Just needed to vent!
