Heavy D-Lift = Emotional Breakdown

I think I am becoming a freakin wuss.

Today's WOD:

Deadlift 1-1-1-1-1-1-1 reps
Then....
15-10-5Deadlift (250#/185#)
Sprint 200m
Pull-Ups

I did 135 - 155 - 175 - 185 - 185 - 185 - 205(FAILURE)
I am a tall girl. I am a strong girl. Why the hell could I not get that 205 even off the ground. I really showed up today thinking I was going to have a wonderful deadlift, a heavy deadlift. Although my last pr was 165, and today I did 185, I'm still irritated.

There is the 205.. I am staring at it then try to lift it. I couldnt budge it. I got light headed and thought I may pass out. What is wrong with me.

Anyway. On to the second wod. Last week I did deadlifts of 135 3 rounds of 21/15/9... So I thought, today I will do 155 on this WOD.

I lost form on the first round rep 11. I dropped it down to 135.
When I started the run I thought I may fall. I couldn't pick up my legs. But I finished.
The pullups were done band assisted kipping.

After all of that, my time was 10 min 20 seconds. It was the longest time on the board. I was a failure? Where is that line drawn where you are happy with your score because you did your best, and when you want to not have the worst time on the board, but you lifted heavy as shit?
One of the things that does bother me about our affiliate scoring, is they don't tell specifics next to a time.

Did the other people do jumping pullups or pullups with a small band?
Did the other people lift heavy? - if so what weight? (they only post rx if rx'd)

I came home and was depressed. Crossfit can be so impowering, and then it can blow your ego. Maybe I needed that.
