Detachment

I have learned to practice detachment/ surrender and to trust the outcome of
my desires to God. I have experienced some amazing synchronicities and manifestations. However sometimes when I am close to reaching a goal I begin to have a harder time keeping negative thought out and trusting in my higher power. When something is only a concept in my mind it is easier to detach from it and let things work out however it will, trusting in God that the results will be the best for me. But when that concept becomes a real physical thing , ( for example, when I actually meet and start dating my “perfect” mate, or am about to actually make a lot of money) I have trouble letting it go. “What if she begins dating someone else…” ” What if…” I know these thoughts may block stuff from happening. How do you let stuff go when it’s at the point where it seemingly means so much to you
