I’m backpacking a few places in Europe currently. I’ve got nothing but a backpack, 3 outfits and a change of shoes with my work stuff it’s very rewarding and I’m the same type of overthinker ! I’ve got most things planned out but I am taking some things as they come because you can’t plan every second of Europe, it’s not possible. I haven’t even booked transportation to some of the countries yet lol because trains over here are east to book a few days prior or day of. It’s a lot less stressful thank you think I promise…though I think maybe you ought to start with a month or few instead of a year.
You’re welcome ! Do take my suggestions with a grain of salt, I experience home sickness often whilst traveling and I always think it’s silly because when I come back home it takes me exactly 3 weeks to start planning another trip away from home lol. Hope it all works out for you though, I’m all for people leaving their home I think it allows for the kind of personal growth you don’t get at home.
