In more then one way

Today I did not go to work I was so sick, I was awake til all hours of the morning with stomach cramps, the "runs" , vomiting and more.
The last week I have felt not well, I have a lump at the back of my neck and it grew and begun to hurt and with that it feels like I have a huge lump in my throat and it is hard to swallow along with that I get a headache and my neck gets really sore and it is easier for me also to get back pain, I put it all down to stress. I find it hard to swallow and it gives me the burps, same with life, this crap my ex is putting me through is hard to swallow and it gives me more the wind when I think about it!
I am just sick, sick of being ill with stress and I am sick of having stress.
