Heartbroken around Berlin - help me decide where to go and what to do

My boyfriend who lives in Berlin broke up with me. I had tickets to go to Berlin in a week and a half (from the US). I need to go somewhere for a week, can be a cheap ish plane ticket from Berlin to somewhere else or a train ticket from Berlin to somewhere else. I really loved him and am burnt out and heartbroken. I only speak English and a little bit of French and a tiny bit of Spanish. Am not feeling super confident or happy. Idk if anyone has any thoughts. I can’t get any money back for my flight and have the time off work. Not feeling Prague or Vienna bc I went there last year but open to other suggestions. Thanks <3
