Thanks for your prayers and support. I’ve been really torn up over my decision- the thing that I failed to mention in the initial post was that the PhD program I am looking at is out of state and a long distance from my family. Moving away would present the real possibility that I may never see him again.
Since I posted, I’ve been feeling much more at peace and less anxious. It is clear to me that the only thing you can do in situations like this is to lay your troubles at God’s and trust in Him to give you the strength, the will, and the wisdom you do what you must do.
