Bulimia help

Okay so I was on myproana and on the bulimic section and there are pictures of very fatty food to purge. Im an IP and a "normal" dinner would make me want to purge it up. I feel that Im limiting nearly every thing and is leading me to starvation (coffee,soup,malteasers,sandwichs ) I need help fast before I collapse and die from it. Every time I vomit I stop eating which means I vomited up my dinner so I have no dinner left in my stomach. Not sure what to do But when I loose a bit more weight im going to admit myself to hospital for some help
