"I am a different person as opposed to seven months ago"

I am a retired Dr. of Chiropractic and a musician. I just joined this group today. Seven months ago I lost a ten-year relationship. We were engaged for 8 of those years. It was her decision. I was shocked. I had to move out (we were living in her house). No matter what I've tried for the last seven months, nothing is working. I'm on several online self-help programs. I am a different person as opposed to seven months ago, for the better. I can't get rid of her in my mind and heart. I hope this program will help me in this direction.
