Between the stresses in your life, trying to start a new job and all of the other factors, it sounds like your brain is grossly over-stressed. Plus, you are entering the age where PCS symptoms may start to increase due to age.

Do you have access to a Vocational Rehab organization ? many states run them. You may be able to get some help learning how to move forward with the symptoms you are having.

It also may be time for you to consider applying for Social Security Disability Income if you have paid in enough FICA taxes over the past years. Delaying applying usually works against you.

It is a hard decision to make. I've been there and had to give up a lucrative business.

My best to you.
