Do something. Never say stuck.

Sell the business if you hate it that much. Or if it's not worth it, get a job you do like and close it down. Sell tools.

Trade a neighbor services for mowing or for a extra lawn mower he has. Find a teen who's grounded who's parent needs to keep them busy. Might mow for just price of gas.

Ask wife if she needs anything... then give her a special family day. Picnic in the living room, have son pick flowers for her or color her a picture. Tell her you would marry her all over again and make her a ring from twisty ties. Smile, laugh and play.

Take walks with your son or wife if she can. Would be good for everyone.
