depressed and fed up

Woke up this morning with my "twitch" and a tingly right leg and foot.  Foot drop came along the more I walked.  Didn't go to work this morning, but that was planned for a doc appt.  I was scheduled to meet with my GP this morning for my B12 injection and to check my cholesterol levels.  Well, the nurse told me they no longer have B12 vials in the office. If I want an injection, I have to have a script written out by the doc, go pick it up at the pharmacy and then come back and the nurse will give it to me!??? WTF?  Talk about a runaround.  I told the doc to forget it, I will take the OTC B12 and hope for the best. It appears to be a war with the insurance and the doc's office to get the thing paid for.
He asked how I was, which I thought was obvious. I told him that I was having another "episode". Since I don't have a diagnosis, I hate to use the word "flare". As I sit there and twitch uncontrollably. He asked if I mentioned my "twitch" to the neuro. I told him that I had and she didn't have anything to say about it. He said he didn't want to overstep his bounds with what is going on neurologically so he wouldn't address it today.  I asked if he could at least get me a script for Valtrex to treat my cold sore. That, he could do! WOW!
I am so at the end of my rope with all these docs and getting nowhere! I am depressed because I keep having flares and the time between them is becoming smaller and smaller.  I question whether or not I even come out of the flares or if it is just my imagination.  I remember when I had a great remission period and thought that the problems I had were behind me and not gonna come back.  Now I wonder when I will feel normal again!  In the meantime, all the medical bills keep rolling in. They depress me further. All those tests and nothing shows.  I have resolved to not bother going to the ER again.  I can control my vertigo with meds that the neuro gave me. I can limp around my house or use my wheelchair if need be. No sense in wasting money to be told they can find nothing!
