First off, I am glad to hear that you've been checked out medically. That's the first step toward ruling out something serious. If you've had CAT scans, bloodwork, and even a spinal tap, I am fairly confident that there isn't something neurologically wrong with you. That being said, I am also assuming that you've had your inner ears checked? Vertigo and "spaciness" can be caused by an inner ear problem like Ménière disease. So, if that hasn't been thoroughly checked, you might want to consider it. This website might be helpful to check out: http://www.labyrinthitis.org.uk/index.htm
Otherwise, I suppose it could be related to anxiety. If you notice yourself taking very shallow breaths a lot, it can cause hyperventilation, which would lead to dizziness and fatigue. Let me know what you think of the prior information first.
Well, inner ear disturbances (which can make you feel "drunk" all the time) can be triggered by any number of things, including a minor trauma like dry heaving. Meniere's disease is "idiopathic" in origin, which basically means they don't know what causes it. Also, an ENT (ear, nose, and throat specialist) will be able to do a thorough examination. Just looking in your ear like a GP would do wouldn't be able to detect a problem.
That said, if it is something like anxiety, a psychiatrist might be able to prescribe something to help you.
i asked my doctor that when they took a look and they said no ugh. well thank you! if i did have an inner ear disturdance would it last this long? and is there a way to fix it so i can feel back to normal?
Can you check out the link I provided (above)? There people seem to be sharing some long term effects that sound just like what you're describing.
Also, unless an inner ear problem is fixed, the symptoms will persist.
Finally, if all is physically well and you feel that the problem is more due to anxiety, there are lots of treatments (both medication and therapy) that are effective. I guess I would just want to be absolutely certain there wasn't some underlying physical cause before I began treatment with someone. I hope this helps some and I wish you luck!
