Is there a chance?

I suffer from treatment resistant depression. Last year I've tried snorting ketamine from the black market. And I didn't see any results despite doses like 270mg much less antidepressive results. My friend says it was ketamine and it helped her with mixed episodes in bipolar. Is there a chance that infusions can help me? I'm panicking I'm resistant to ketamine as well. Like I felt only a bit drunk but without a good humour and that was all. I know I won't get professional opinion I just need your experience.
