Googley, do you have a close girlfriend you can talk to about personal stuff? I have one good friend that I can talk to about anything, and I mean ANYTHING. Books are great, but there is nothing like real world wisdom and advise.
I have a daughter just a year younger than you and I am (happily) amazed at the questions she feels she can ask me. She always says..."this might be TMI...BUT..." and asks me whatever it is. Heck, I'll be your "surrogate" Mom in that role if you want me to. PM me anytime.
