I Have a Broken Heart

I am here in Holland, thousand miles away from my home, for my job, having a hard time to be productive in my work and make local friend. On top of that today my ex text me that she is getting engaged to some guy she knew from her college and asked me to forget about her (after all that 5years).
I can't feel any more shitty and morbid that I am right now. Can anyone with some experience give me some ray of hope, or something that give me my life back on track?
