*hugs* Yu can do it!
I try to keep myself between 1400 and 1600 calories a day. It doesnt sound like a lot, especially when you are used to eating a lot more, but when you eat a lot of healthy, low calorie food, you'll be surprised - Ive had days when Ive eaten some nuts just because it was the end of the day and I wasn't hungry, and I was under calories!
Just remember to keep track of how you feel once your adding in exercise... it may be that you will have to tweak your plan and add a bit more calories.
And, of course, we are all always here for you!
