3 weeks out till first competition

Okay so this is how I look like at the moment (or slightly softer as I just had 300g of choco wafer sticks...Oh Lord...)
I only have 3 weeks before my first bodybuilding competition. I struggle to get my bodyfat % down, I'm still holding 20% which is not very good at all but I'll try...Cat said my competition weight should be around 49kg, so I have 4 kg of bodyfat to lose...very challenging...
I'm really good with my weight training and I have to walk at least 45min first thing is the morning, 6 days a week. It is my diet which is a big challenge; I have crash days every now and then and everytime I crash, I eat WHATEVER!!! I think I've consumed over 1000kcal from chocolate and cookies today...
So this is how I look, I can see my abs most of the time when I suck my tummy in and my shoulders are wider, my legs slightly more defined (but still look like 2 huge chunks!) However, I still look too soft compared to other figure girls...I might have to compete in a lower category which is body shape...Who knows how far I can get in 3 weeks time anyway...just wish me luck and stop me from buying those junkies...

Thanks!
