Getting Sick & Tired of Being Sick & Tired

Here it is, 17 Apr, a beautiful Saturday and I am laying in bed, where I have been since 29 Mar. Not good. But I don't feel much like being in life right now. Literally have been in bed since 26 Oct 08 when I was given only a 10% chance to live when I got pneumonia and had to have emergency surgery and was in an induced coma for 5 days and then in Intensive Care Unit for 9 days. Two more weeks on the surgical floor to get stabilized then a month in the rehab ward. Couldn't do much there due to numerous other physical problems. Was sent home on 18 Dec 08. Sort of started coming better until May 09 when I was literally dumped in bed due to the worst depression I had ever known about. I didn't want to live even. Met up with a mental health nurse who literally helped me crawl out from under the mountain. Now she is going to a new job and won't be there to help me any longer, and just when I'm starting to crawl back under the mountain again. Don't know what I will do?
