Your depression is certainly treatment refractory. I would contact the nearest university teaching hospital where the latest protocols are used. If you have insurance and can arrange to attend a facility like the MAYO clinic all the latest medication protocols can be tried. There is a treatment that is being tried experimentally at Emory University in GA which is similar to ECT, but without the convulsions and short term memory impairment that you may wish to try. Contact NAMI for information on how to get the treatment that you require.
Best wishes and good luck.
