I'm not a pro, but I would like to help and have suggestions.
The thing that jumps out at me the most is your 1000 calorie intake. I'd say that is way to low for your activity level. Plus your use of stimulants is probably draining you even further. Further, if you're eating super clean, it might not be helping the situation either. I'm not sure exactly what you mean by super clean, but make sure your diet is not lacking in fat. Also, your sodium intake at this point should still be moderate, and you don't need to worry about salt at all right now.
I'd really recommend getting that calorie intake up. Start to eat more, and get up to at least 1600, and see how you feel after a week of that. If things start going better, keep that for a while, and then gradually decrease about 50 calories per week in the 5-6 weeks leading up to the show. Don't go below 1200, and if you reach a condition that you are satisfied with, do not make any changes at all to your routine and just coast along until the show day.
I'd also try to stop all stimulant use for about 4 weeks or until you get your diet fixed. You might also look into Reset AD (http://anabolicminds.com/store/1334.html) and use that if you think you will benefit. And only start using stimulant and fat loss products again in those remaining few weeks if you're not happy with how things are progressing.
Try not to worry. You might have gotten a little carried away with your contest preparation and tried to take on too much, too soon, but you still have lots of time to figure something out. And so long as you are feeling better when the 10 weeks is up, even if you're not looking like you want to, remember that you have a lot of life left to get where you'd like to be.
Also, welcome to the boards. Please keep us updated with how you are doing.
