Hi everyone, I am new to this forum

.
I have had balance problems for the past 4 years now,
it all started when I had a very dizzy spell whilst driving around a round about.
Then I started getting ear pain and a buzzing in my left ear.
My doctors told me i was getting panic attacks.
Things got worse, I started getting more daily dizzy spells, I felt off balance alot, especially walking down the street or when its windy weather.
The floor sometimes moves, like it shifts very fast to the left and my head feels too heavy to hold up, its like its being pulled towards the floor and then I get very scared cos Its so dramatic, I feel I cant focus on one spot.
Also when in the house , if I look up at the clock I feel like I am falling backwards very fast, sometimes in shops I get overwhelmed with all the movement going on and get dizzy.
2 weeks ago I had 2 ear infections (in both ears) and the doctor gave me antibiotics which has cleared it up, but this week Ive been told I have a white milky fluid behind the ear drums and that I am being reffered to a audiologist.
what could this be ?
My dizzy spells come and go daily on and off, sometimes I feel slightly sick when it is really bad, Im now too afraid to leave my house, I absolutely hate living like this and would love to know what is wrong with me.
