Pain after and in between meals

Sorry if this crosses into too many topics, but I have been dealing with severe stomach discomfort for several years now and nobody can give me any answers. I suffered from a rather extreme case of anorexia and for about 2 years lived on raw vegetables, tea, sugarfree jello, ibuprofen and splenda. since "getting better" i have had persistent stomach pain. I am always bloated after meals, but there is a gnawing pain in my gut that lasts pretty much 24 hours a day. Certain things seem to make it worse, so I have made many modifications to my diet. I have tried going wheat free, dairy free, everything I could think of. Still pain. It has been several years since I began eating again and food still makes me so uncomfortable that I have developed a very bizarre eating schedule so as to "work around" the discomfort.

I have seen several doctors who have bandied around theories of IBS and done a few scans but nobody has been able to rid me of the pain. I avoid almost all medications, OTC or otherwise, so taking more painkillers has never really seemed like an option. I also suffer from extreme anxiety, which cruelly messes with my appetite to the point where food is almost intolerable, but the pain preceded and may have helped trigger that anxiety so I don't think that is the culprit. I now manage to eat 2x a day but my weight is still low- 5'4" and 92 lbs. I want to be able to eat again but if every meal lays me low it seems unlikely that I will ever be healthy. At this point I have seriously considered suicide- to be in constant pain is not a way to live, and the fact that the pain is "invisible" and thus nobody seems to understand why I sometimes behave oddly after meals only makes it worse. Again my apologies for rambling but I don't know what to do. Any input would be much appreciated.
