How do you get out of a dark place?

so I am now on my 9th major foot operation and in bed for the next 5 weeks,in just two weeks I have been to the hospital twice for pain control,been sick to my stomach,have dropped contact with 3 friends and have experienced more heartache than I know what to do with...My life is coming apart before my eyes due to another female,somebody my man just can't control himself enough to stay away from,I have forgotten what it's like to live happy...How do I get out of this dark place that I am in,I just want to sleep and cry right now and no amount of sleeping pills is helping me...
