I am so sorry. I have no specific advice to offer because we are at opposite ends of the spectrum, but I do have lots of sympathy and prayers and hugs for you. IBS is totally soul-sucking. Please don't let it get to you like this. Your life IS worth living. Things are rough now, but they WILL get better. There are a lot of people here who really care about you. You AREN'T alone.
One thing is imperative -- YOU NEED A NEW DOCTOR. If necessary, start out with a new GP instead. Go find a female doctor -- they tend to be more sympathetic. This GI is a moron and a jerk, and you don't need to be helping him pay for his Jaguar payments.
IBS-C is a tough beast to tackle. Don't give up hope after 10 months. Don't give up hope, period. If you are feeling desperate, go to the ER.
We are all thinking of you. Please hang in there.
