As Christians we too often think we have to be "perfect". Your feelings are real and valid and do not make you any less "godly." It is alright to get the professional help that you need, whether that be hormone replacement, an antidepressant, or a few sessions with a Christian counselor (many insurance policies do pay for this). I have found myself in a similar place (although not by my daughter's choice, but by her sudden severe medical illness). I was deeply disappointed and depressed about the loss of the future I had planned for her. I really struggled with allowing myself to even fill a perscription for an antidepressant, but once I did, I discovered that it helped me "get over it" and I only took it for a few months. The most help I received was from a Christian counselor. Your pastor should be able to refer you to one. (this is a professional licensed couselor, not a layman) Most importantly, even though you're very disappointed, do keep a relationship with your son and his fiancee. You don't want to end up being left out of their future life together. Just "be there for them" and let them know that you love them. That can go a long way in healing. I will be praying for you D..
