If you're nervous about tanking (and I totally understand why you would be), you could always try to put together a group of friends to go with you over a standard pug. It helps when you're running with people who know you're learning, trying your best, and are willing to forgive mistakes. They may tease you along the way, but that's all in good fun, and can be a good bonding experience beside.
You could also consider seeking out a tanking mentor. Someone who knows the fights, has an eye for pulling and positioning and is willing to run along with you and teach you. I'm sure someone here on the RPC would be willing to help if you don't have someone in mind already.
I get nervous about new dungeons and raids too. I never want to the be that one dumb DPS who fails understand the mechanic or dies to a telegraphed move they should have seen coming. I play super serious when I first step into new territory, and stress myself out. It takes a few runs before I relax. Once I know what to expect and what to do, I can actually enjoy it.
You may find yourself being able to relax once you get used to things too. In the mean time, don't be so hard on yourself and don't push yourself so much. :3
