Bilirubin symptoms and conditions

I am a 54 year old male who was prescribed bactrim by his ENT for a staff infection. I was taking 3 pills per day after each meal. I had no past health issues and never have been hospitalized. On my 8th day of Bactrim, I had major head pain, pain so severe i was vomiting, and lost 20 pounds. I woke up the next day Jaundice. I took a blood test and my alt hit 800, ast hit 500, bilirubin was 6.5, blood in my urine. Now, 5 months later and of course, off the drug since mid-July, my level alt level is still 240 and ast 140. These levels are way too high, and now need a liver biopsy. My GI doctor tells me unlikely that this was bactrim induced, right! Please, I never had a problem until taking this medication, and now who knows if my liver will ever return to normal and what other health issues will now take place.
