Pro-ana help...........?

I don't care if you're here to tell me how wrong I am for the lifestyle I live. My mind is already made up and you won't be changing that. I'm just wondering how many cals most anorexics eat daily? Would it be okay to have LOTS of water, diet coke, plain tea, and 1 can of soup (80 cals). I feel like that's a lot. I know anorexics DO eat I just don't know what to eat. I just don't want to gain weight. Is the soup too much?
