You are currently caught up in one of the three most stressful events in life. Please try to remember that your worth to society is not measured by how many amps you possess, how large your speakers or house is, what type of vehicle you drive, or who you may work for.
You have one child who aspires to be a doctor, and is progressing. Another who is advancing in high school. These are your prizes. Showing them how you deal with your current adversity will be a much better life lesson for them than expertise in organic chemistry or physics. I say this from experience.
When I retired from the Army I flailed about for a few years doing contract health care work. (I was a medic in the Army) This action paled so I switched gears, and retrained into the tech industry. It was a rough two years. But now, 20 years later, my kids have told me how much watching me deal with the situation has inspired them.
I am not suggesting that you switch jobs, retrain or anything like that. Advise like that from a 62 year old who can't afford to retire is worthless. I would just like to give ya a few bullets:
-try not to get too cranky. I did and it was a rough two years
-remember yer family still loves you. Tell them you love them back.
-home theaters are a luxury. Two channel is a necessity.
-people here like ya, and will give ya support. Use this support.
I can't really figure a good ending to this sermon, except listen to and lean on your family, they probably love ya, and that can't be beat. Recognize your end game goals, and make a decision based on that. Good luck. Keep us advised.
P.S. "It don't mean a thing if it ain't got dat swing"
