You certainly have been thinking about your situation and I think you are on the right track w/everything. Set your boundaries as needed.

You are absolutely correct w/the analogy about pulling the plug and there is still grief. You'll have moments of grief for quite some time and it's normal.

You have a "can do" attitude and that's what is going to shine through wherever you go. You have goals and I have no doubt that you will reach them and go even further beyond them.

I hope today is a good day for you.

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.
