For the past few weeks I've been having a craving, nothing will satisfy it, I don't know what I'm craving but it's just a feeling that's always there. Is this a symptom of depression? My GP doesn't take it seriously and I've been 3 times in the past year about depression. I feel as if I've tried everything and there is no hope for me.

At this current point, I'm out of a job because of my mental health, I have only been sleeping for 2-4 hours a day, my life is going downhill fast and it just seems to be getting worse. My head is a mess and I can't think straight and to be honest I can't feel emotion anymore.

I need help but I can't get it, any advice? What am I craving. How do I get my doctor to listen to me.
