Lily, I relate to everything you said. I was you. Then at 50, after making peace with being single forever, I met someone and got married. It's been nine years, but I remember those tough single days like it was yesterday: the inferiority, the frustration and pain. The struggle is real! The best piece of advice I can give you is to breathe through it all. Life can change in an instant, love can happen when you least expect it, and yes, tomorrow you will feel better and have a different perspective. Wishing you all the best!
