Seconding this. Worse comes to worse, having a regular GP write a prescription and helping you is better than nobody helping you.

Have you tried looking outside your city/area for help in maybe a neighboring city/area? A little road trip is better than not getting any help at all.

Otherwise, I'd advise going to the ER. Seriously, if they think you're a danger to yourself, they're more likely to help and they may be able to refer you to someone who CAN help and who meets all your criteria.
