My depression is crippling?

My mother died last Nov. Since then I've been getting very ill, depressed, and no one understands. Don't get along with family, there's a lot of dysfunction there, can't depend on them. Husband withdraws when I am in trouble, the worse the trouble, the more he withdraws, or wants to help with tough love. I have exhausted all help from the community, no one can do any more for me. Meds don't help. I have multiple chronic conditions that cause lots of pain, which have worsened since mom died. I feel all alone. No one to understand, no one that I can go to for help. I feel like my only alternative is assisted suicide in Switzerland.
