being bulimic yeah i think i would have tooth problems but still very nervous..

my tooth is the bottom eye tooth. very sharp since i filed it and very sore. Its not the tooth but the gum around it. Its swollen, the tooth is loose, sensitive like when u loose a tooth and u feel the gum area were the tooth was, yeah same feeling. The gum bleeds when brushed (whats new). Ok this started when i got a apple skin stuck inbetween and i was picking inbetween the eye tooth and the front tooth (you know the tooth next to ur two bottom teeth that are right below two front buck teeth) well i got the peel out but its been tender. I thought it would go away by now but it has been a week now. My gum is swollen and feels weird. I have no dental insurance and the dentist in the family lives 2 hrs from me and i have no money to go to her cause gas prices are so high.

Any one have this problem before, and what should i do for my tooth? i hate to loose it.
