I am so glad that you returned and posted an update. Congratulations on the new job! I can't believe your oldest son is going off the college very soon.
You have come such a long way from the frat boy in the basement and the fake palm trees and Christmas trees. You have earned a gold start and an award for dealing w/so much along the way.
I am so very happy for you and your sons!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
