Please, someone tell me to get over myself.

A friend of mine who is ALWAYS competing with me (and who has an opinion/answer for everything) just announced tonight that she is going off of BC, and that since her family has a history of being 'fertile myrtles', she'll probably get knocked up rght away. She knows the struggles we have been having over the past year, and she has always said that she's going to wait to have kids.

I know that I need to suck it up and just be happy for her. However, I know that if she gets pregnant before I do, she will make my life miserable, giving me tips and hints on how to get pregnant the 'right' way. She also has a TON of money, and will most likely buy all the best things for her kid...and make me feel inadequate for not doing the same.

Right? I need to get over it? How have you dealt with similar situations? What should I do/say?
