It doesn't sound like you are healthy, very few adults can manage to be healthy at that low of a weight. You need to figure out who can help with the stomach issues so you can get back to eating.
Your last post you were doing some pulmonary tests, did that come back with anything to help you?
What medications are you on, how long have you been on them, what symptoms do you have that are not being controlled? Do you need to consult another primary care dr or rheumy?
Do you have a therapist or psychiatrist? It sounds like you might need some help dealing with what is going on and figuring out who can help...this disease can lower our spirits to the point of not seeing clearly to find the help we need.
