Entire world was flipped

I have posted my story so many times so I'm sure you are familiar. If not let me know and I can go into details. 6 year relationship ended two months ago and I lost a lot. His family, my home, the house we were about to buy, him. My life basically started over and I just can't get myself back together. I lost my best friend, partner and love of my life. I just don't know how I can come back from this.
