Where do you go if your dermatologist doesnt know what to do?

I have had a really embarrassing skin problem(face) for over a year now.
I have been to so many skin places from one dermatologist to another, beauty clinics and other places. And recently i went to a new skin specialist and i pretty much paid him $150 for him to say i dont know what to do or how to help you. So now im at a dead end no one knows how to help me im at the point where i thought of suicide the other day.
Anyone know where i can go to get some SERIOUS help?
Please im desperate I mean my life is ruined. too embarrassed to get a job pretty much hiding from everyone.
