How did you navigate your life after it fell apart?

Basically the title. How did you manage to navigate and reinvent your life when everything fell apart?

I (F) am living in foreign country. I have developed a fairly good career over the years here. Recently I broke up with my fiance and all my/our plans went to the bin. I am mentally in a better place now. I have a lot of hobbies and friends but I feel confused and unfulfilled in life. I wanted to start a family in 2 years which is not happening now. Sometimes I am thinking to move back to my own country or stay here. I don't have super strong relations with family unfortunately so I'm worried this might not change much (changing the location) I am not sure how to navigate my life properly now. I am worried I don't have enough time to meet another partner and start a family. I am not sure what to concentrate on and what next steps to take to figure out what I need from life. I cannot really rely on my family for this advice hence I am asking here.
