Haven't felt this bad for ages

I have been feeling a lot worse than usual lately, but this week has been very bad. So much so that I have made an urgent appointment to see the doctor. With an urgent appointment, you have 5 minutes and may discuss only one "urgent" problem.

I have 3 urgent problems, so I will throw a dice to see which "urgent" one to tell the doctor about today, and I have made a "routine" appointment for the 18th April. In a "routine" appointment, you are allotted 10 minutes and may discuss more than one problem.

I feel spaced out and dizzy, like you feel just before an anaesthetic finally knocks you out. I have asthma made worse by a chest infection, and severe menorrhagia. My ME symptoms are worse and generally, I feel truly terrible. My pain levels have shot beyond the relief that my usual painkiller provides. My house is a mess and is getting on my nerves, but I don't have the strength to tidy it up, let alone clean it. I can't sit at my computer for more than 10 minutes, I can't go shopping and I can't even read a book.

I wish I knew what I have done to bring this mess about, but I can't think of anything. It would help if I could because then I could avoid it in the future.
