Sorry for the long post, but any opinions would be GREATLY appreciated

Looking for anyones opinion as I'm at the end of my rope here...again...
It began in January 05 as I woke up one night feeling really dizzy on my left side, I turned to my right side and it didn't go away I sat up and opened my eyes and everything in the room looked like it was jumping in and out at me. It stopped a few minutes later. The next day and for a month after I was really dizzy. I was pregnant at the time and the doctors chalked it up to hormones and "get some rest". The constant dizzies went away but I had frequent dizzy spells. Toward the end of my pregnancy my head constantly felt like it was spinning especially when sitting or standing still. Laying down was the only thing that helped.
After my baby was born in July three nights of no sleep followed by five months of lack of sleep really set me off. Long story short, here are my symptoms..
Feeling like I'm walking through space
Right leg feels as if I just took off my rollerblades and now it feels really light (if that makes any sense). Not numb or tingly but like I have to concentrate to make it move when walking because it feels so light. I find myself curling my left toes when walking. Also my left arm often feels like this. I have control, but it feels like they are in space.
Constant spinning head feeling especially in the back
Blurry vision sometimes especially when dizziness is worse.
Things look like they are moving back and forth.
Constant head pressure especially at the top of the left side of my head.
Headaches/migraines.
Left ear clogs when I blow my nose.
Left ear sounds like tinfoil being crinkled when I hear loud noises such as people talking loud or my baby crying.
Head feels like it's being pushed back and forth when I lay down.
When upright head feels like it's going back and forth and actually physically does move back and forth, very disturbing. Sometimes in bed the feeling moves down my neck and left side of my back.
Tinnitus.
Constant fatigue. The more I do, the more tired I am. Feel like I could sleep for days.
Anxiety from all of this along with controlled depression from not being able to get out of the house by myself except to go on short walks with my baby.
Every time I think it's getting better, it creeps up again, arghhhh.
Started Lexapro about 1.5 months ago which has significantly helped the depression and most of the anxiety and some of the dizziness, but the rest remains. MRI results normal. ENT visit worthless, said she didn't think it was my ear. After the deppresion and anxiety creeped in doc said "postpartum deppresion". I say "post-dizziness depression".
Can't decide if it's ear or migraine or something entirely different.
I know this is a long post with a lot of symptoms but any advice or opinions would be GREATLY appreciated.
Thanks a bunch
