Prep advice for first comp

I'm a three stripe white belt and have just signed up for my first comp in Feb. I'm absolutely terrified even though my teammate are really supportive of this.

I'm fine with loosing my first comp as that's normal but my main concern is that I know I got most of my stripes out of sheer resiliance. I roll with anyone and have spent most of my year of training being the only girl so it means I get tapped out and keep going back in for more.

This means I spend a lot of my time on my back under mount, with someone on my back or fighting out of guard. My defense has really improved in recent months and I know I'm hard to choke or arm bar but my attack is weak and I'm worried I'll just loose on points.

I'm going to start asking the guys to ease off on me a little to see if it will give me a better chance to try things out but I'm just nervous that I'm going to compete and draw a total blank on the most basic attacks because I don't get enough practice in real rolls.

Any advice would be greatly appreciated!
