I'm hardly a "real" cyclist, but I will say that a lot of cycling is mental. You'll get some great training advice from other ladies here that will help to improve your stamina, bike handling, pedal stroke, etc, but the first thing to do is squelch those doubtful comments in your head. You're going to have bad days. You're also going to have awesome days when you feel strong, empowered, and can't imagine having so much fun doing anything else. Hold onto those days, and learn whatever you can from the bad ones. There's no reason you can't aim for any goal on the bike that you choose to set.

When is your RAIN ride?
