A good lawyer is not of any use to you if the state you are in is unfavorable. Or if you really did fuck up and get caught and she has evidence.
Children leaving home can be a trigger as well. You are no longer "needed". It indicates that you are now facing your own mortality and "golden years" while they are just starting theirs. A lot of yearning, inner reflection, and wishing you had the chance they have now again can fuck with some people.
Some people just do not look good with bald heads. There is a certain head shape that is ideal for being bald. Shawn Ray had it. The Rock has it. Most people do not.
There are a ton of things that can suddenly come to the forefront act as triggers. Being stuck in your job and not liking it anymore, but realizing you have invested too much time in the business and do not want to change careers so late in your life or go back to school, loss of a parent, debt, seeing other people you know more "successful". Usually whatever the case, it helps to see a therapist.
