Please tell me your stories of finding new love after you thought it was impossible

If it all seemed hopeless and you thought it’s impossible to move on but you were forced to do so. The love we had was so special. I am 31 and I feel like I’m dead. I have lost all my friends, I feel like a lost cause. All my life i wanted my own family and true love but it seems impossible after such an immense heartbreak with the person whom you thought was the one. We had such a strong emotional connection, we had our own world, our own language, amazing chemistry… he left me because of my insecurities and low self-esteem.

Where or how do i even start?
