While it isn't really straightforward, Spotify support will transfer all your songs, playlists, followers and if I recall correctly also your followed artists to a new account. Another possibility is for them to delete your old Facebook-linked account so you can create it again after which they'll also transfer all your old data. It isn't an ideal solution but at least you won't have to worry about losing your collection.

Do you want to tell more about your time in Nepal? What did you do there, where did you stay and did you go there by yourself?

I’m not the parent commenter but I recently spent almost a month in Nepal. Most of it was trekking in the Annapurna region. There are “teahouses” along all the trekking routes (some areas have more than others), which are mostly very basic but very cheap. I wasn’t alone but I met many people who were. It’s easy to befriend other people on the same route and stick together for awhile.

Aside from trekking I spent a few days in Pokhara and Kathmandu (Thamel), but much preferred the mountains to the cities.
