I would consider having a special meeting to discuss freely the situation with your work peers. I am convinced that the taboo surrouning BB makes it worse.
Let people know that you are aware of your situation, that you have tried so far everything that was recommanded without success and see if you can find a solution altogether.
I know it is really hard to do but it will desinflate the snowball effect.
And if you don't tell them, they will get to notice your BB anyway.
Don't let BB have you to quit your job or you're soon to quit life.
BB is a handicap, but it is not as obviuous as a mutilated limb. We have to inform people about it.
