OP, sorry you are not feeling well. As other PPs have said, your illness may or may not be from the flu vaccine. Please don't let this stop you from getting the flu vaccine in future years. You likely won't have the same effects with later flu shots. The benefits of the flu shot are substantial.

With each flu shot, you gain some immunity to different flu strains. I recall when the swine flu outbreak occurred in 2009, older people actually did better as a group, because they had some prior immunity to that strain.
I personally had symptoms similar to yours last year, after I got the Flu Mist. They were a real pain, but the went away. I was reluctant to get the flu shot this year, but I eventually did. No side effects at all.
