Shift Swap

Monday, Saw me back at work, this is not my shift and wasn't even on my station but as I want next Sunday night off I asked some people if they would swap a shift with me and this is the shift I am doing in exchange,
I was working about 8 miles from my usual base so I knew the area fairly well, and my crew mate was someone I enjoy working with, he's a paramedic and quite crazy!
Ben and I started our shift by going on cover followed by a couple of jobs, one of which was to a 17 year old who last July had been a clothes size 18 and decided to diet, well she was now a size 8 to 10 and very poorly, she had been diagnosed with Anorexia, and when we got to her she had a slow pulse, very low blood pressure and a blood sugar level of 2.4, She declined to take the glucose food stuff we have for raising sugar levels (average is 5) so the next stop was an intravenous glucose drip, Ben tried to cannulate but her veins were poor, so, step three was Glucogen a drug which is given as an injection into the muscles usually in the top of the arm, but in this case there was so much risk of getting a blood vessel we went for thigh, I gave the injection waited a while then tested her sugar level again, it hadn't come up by much.
We got her into hospital where she was able to get the help she needed.
Every one of our patients had a delay in being seen today, the longest delay was for two and a half hours, for the whole of this time we were stood waiting for a bed to transfer our patient onto from our stretcher.
We managed to finish on time and just as I was about to leave I got a message from one of my colleagues saying she had the results of the post mortem on the 3 year old resus we had on the 5 Feb. She asked me if I wanted to know and I said I did. She told me made sure I was ok then we ended the call. during this time Ben had also come over to see if I was ok as the results had upset me. I told him I was fine then phoned Tepic my normal crew mate and asked him if he wanted to know.
Why is it that when you really need your husband to be at home he is at work? We talked on the phone though. I drove home.
An almost relief washing over me as well as shock at what the post mortem had found.
