I have BPPV, benign positional paroxysmal vertigo. I have symptoms the same as you that last for weeks at times. Have you been screened for it? It is fairly common to have it. It's related to the condition of your ear canals. It's been explained to me as debris in my ear canal. In response to Cheryl V, I also have allergies but I wasn't told the two were related. I'll do more experimenting with decongestants. I had that long list of tests and was also told there is not a neurological reason for the dizziness.
Since you've seen the doctor about this, I want to reassure you that your dizziness is very much unlikely to be related to anything life threatening. Although dizziness can be a symptom of a stroke, this has been going on long enough that you couldn't possibly still be suffering from a stroke.
Physical therapy can help with it. However, the exercises that supposedly reduces the dizziness does increase the dizziness for a long time before it works. There is a maneuver, called the Epply Maneuver that has ended my dizziness. It's performed by a physical therapist.
I was referred to an ear, nose and throat specialist. They have a fancy name that I can't remember. I suggest that you get treatment thru a specialist.
I take Ativan for anxiety, as needed. You can still take care of your kids while taking it. If it makes you groggy enough you don't feel safe take a smaller dose. I start with 1/2 mg. I urge you to try the Ativan. If the Ativan takes care of it, I suggest it's the anxiety causing it in which case your anxiety over taking the Ativan is hurting you.
