Constant chronic Dizziness

Hello, please read below:

I have been suffering from chronic dizziness /balance all day long for over 6 years...i'm male 37 years old now....i did all the imaging and blood work and nothing was abnormal...

I notice this:

1- If i see a person i don't like, i get more dizzy andi lose my balance more and i get brain fog
2- At work, i cannot leave my chair because once i stand up i am disoriented, so i should be sitting on my chair all the time for 8 hours !!!!......the only time i can stand up from the chair is to stand up and immediately WALK.....i must walk because if i don't walk i would lose my balance and feel more dizzy.....
3- When i walk, i pray and hope that no one stops me to talk to me because if he stops me, i will lose my balance and get more dizzy and more brain fog!!.....
4- If i go to take money out of the ATM machine, when i bend down i get so dizzy too.....especially if there are people behind me waiting for me...if i am all alone and no one is behind me sometimes i don't get dizzy....so it doesn't happen all the time but since ATM machines are in busy areas, i would always always get dizzy
5- Whenever i drive my car , i am extremely normal....when i debark (reach my destination), i get soo dizzy and disoriented
6- The more sad/depressed, the more dizzy i am
7- When i keep my mood elevated by thinking very positively, the dizziness goes down
8- When i get bored and i feel there is nothing that pleases me anymore, i get more dizzy and more imbalanced
9- After seeing a nice movie, i would stand up and my balance would be much better without the need to walk.....but after some time, i lose my balance again (once the nice movie effect goes away from my brain)

I just don't know how to keep my brain positive.....i always tried to, but i cannot because there are bad days that happen to everyone who is not dizzy.....so such bad days would put me back down to the time when i started to think that i am already better !!!! and hence i am dizzy again from zero !!!

Can anyone help me figure out my problem please ?

God bless you all
