Suggest Treatment For IBS, Nausea, Depression And Vomiting

I have been suffering with a condition for seven years. I have been diagnosed, this week anyway, with IBS but have only ever been prescribed anxiety medication to help with what I can only describe as horrible bouts of pain and nausea before, during and after a bowel movement. I have never been prescribed, upon research brought on by extreme frustration with my care, any of the usual medications available to treat IBS symptoms. Nor have I been given meds for nausea or pain. I continually ask for help with the symptoms, IBS or not, have taken everything they suggest for depression and anxiety associated with chronic suffering including seeing a psychiatrist. I am certain, especially after today s visit to the clinic, that I have been unfairly and permanently detrimental to my physical and mental health, profiled by several doctors. I have been treated like a drug seeker, yet have no history of dependence and am willing to undergo any drug test, been accused after three days of vomiting brought me to the ER that I brought it on myself by self-medicating. I have tried to point out that if I had help I wouldn`t have to self-medicate in the first place. I have also tried pointing out that I came because I was too sick to get out of bed or off the toilet, let alone take whatever pill or do whatever other drug they think I am doing. Please, I am at my wit`s end, how can I get fair, unbiased treatment without some strange doctor accusing me of something that another doctor wrote in my file WITHOUT proof or evidence? I really cannot take the pain anymore, it has taken over every aspect of my life and I do not know how else to ask for help.
