Sorry, I'm just trying to be encouraging and to challenge the belief that there is no way out of this situation. It's fun to hack the brain, and to submit your lower brain systems to the will of your conscious brain. The short term may be hard and painful, but in the long term you'll feel better for it. It's not that different from studying hard or exercising.
This is my humble opinion, and your mileage may vary...
It's been noted that people with Aspergers sometimes have a problem with certain food textures. So this could be a manifestation of that.
