Getting over someone you truly loved....how on earth is it done?

One day, I'm thinking no problem I've got this covered.

Next day, I'm thinking what if I had said something different?

Next day, I'm thinking surely I can love again.

Next day, I'm positive I will die alone, unable to ever give my heart to another man.

Next day, I cannot even look at men, because he is a man, and therefore they remind me of what I lost. Why do they exist? Get out of my view!

Next day, I destroy the treadmill. No one has run that hard, for that long, on the damn thing since 1999.

Next day, all I need is a cup of coffee and I'm happy.

Next day, I realize.....I still love him as much as ever.

How is it done people? How do you get over true love?

Advice?

Shopping? Tried that. Spa? Tried that. Move? Well, I live in Turkey. Clearly tried that. Hug my cat? Tried that. Be patient? Yeah, I know. I'm working on it....
