I plan to much for everything.

I have OCD and I'm trying to defeat it. I also don't have a social life and I'm lonely. I want to meet an amazing girl one day but I'm trying to make improvements in my life. I plan stuff like what age she'll be (I usually picture her from my age to two years younger). I know I can't plan everything and the best moments in life are moments you didn't plan for. What do I do?
