First I would like to clarify that I'm not looking for medical advice.I know some people will say to go to the doctor, but I already have. 

Anyway...

The reason I post here is because I know for certain that my "dizziness" was caused by anxiety.

Sounds absurd but I will elaborate. 

About 3 years ago I had something akin to a panic attack. The anxiety had been piling up for a while. I was tense and even felt zaps on the back of my head (I don't take drugs btw). There were family problems and it somehow overwhelmed me. I felt like something stabbed the back of my head and for about a second or two felt to room spin. But unbeknownst to me this day would lead to a downward spiral and been dealing with this constant annoyance for 3 years now.

From here....Doctor visits, work problems etc etc etc... Not important. But a huge waste of money and has left me without an answer....

Now here is where I want to elaborate on the kind of dizziness I feel. Since there seems to be a variety. You guys should look it up.  

1. This is Not the spinning kind or lightheaded ness type. It is more a sense of unbalance. I can walk straight and all but for some reason I feel the sense of unbalance.
  - When standing I feel on occasions that the floor moves and the occasional feeling.

2. The vexing part is that I feel when laying down. I feel like I'm sliding down and with it the sensation of falling.You know that jolt you feel when you slip or fall, that but a bit milder. But annoying.

3. Sometimes, when I sit I feel like I'm swaying. This occurs when I go to restroom and sit. 

4. I want to add that the zaps on the back of my head stopped a long time ago.

Now this has consumed my thoughts and my time since no doctor has given me a proper explanation. I've been searching a lot websites for an answer but there is so little about this.

Though I have learned to cope, somewhat. But it can be distressing, sometimes.

I guess I post this to vent or to catch people that may have this problem.

 I'm only 30 and it's quite amazing how something that seems so small and redundant can affect my life.
