21andTTC#1-- sending you a big HUG...so sorry for all the stress you are dealing with...
plus having your friend be pregnant and be so casual about it must be very very hard to handle...I can imagine I would feel the same way you do...plus your buddy nurse as well!

all your frustration and anger is very understandable, and so many of us have felt the same emotions...it can be hard to find people who do understand, but at least here, you will find support. Try and find ways to relax through acupuncture etc- it can help calm your mind and body if nothing else. And remember, you arent doing things wrong...sometimes some people just take a long time to have a baby.
