Vertigo, or dizziness, usually results from a disorder in the peripheral vestibular system (i.e., structures of the inner ear). Dizziness also may occur as a result of a disorder in the central vestibular system (i.e., vestibular nerve, brainstem, and cerebellum).
Your husband may also be trying to hide his true income to help him obtain a lower child support and an alimony award. It is your responsibility and of your lawyer to try to uncover any hidden monies, and to prove the actual amount of money that your husband is truly earning.
Even if you think you have hidden your marital problems from the kids, it is likely they know about them. Because of this, it is important to discuss an impending divorce with your children, to explain what is happening and to let them know they can talk to you about their feelings.
