Solo travelling after a break up?

To any Bojack Horseman fans out there, remember the episode where Diane goes to Vietnam after she gets divorced? That’s kind of me right now. I panic-booked a solo trip to Berlin for next week after a break up as a way to keep my mind off it, and I’m worried that I’ll feel lonely and not really into it. It’s my first time travelling by myself which I think is pretty scary, as well as already feeling quite fragile. Any tips or words of encouragement on how to have a little self-care holiday or just how to be alone in a foreign country while not feeling too beaten down and lost? Sorry if this is vague or a non-thing to worry about, but yeah I just don’t want to feel like I’ve wasted by time and money if I’m not super into it or if I’m thinking about the break up too much to enjoy it. Thanks guys :)
