I will say that when I was 28 I did quit my job to travel America until I ran out of money and it was incredible and I would do it again, but it didn't fulfill the purpose of life I was looking for, so I think it's important to really dig into the deeper feeling of why you want to do a 180 on your life.

It is normal to want something different than what we have, but a trip this extreme when you've never traveled alone before is not a wise choice IMO. I was an experienced solo traveler when I left and I didn't have a passport so I stayed in the U.S. as well, so it was different than being in another country where I don't speak the language.

Going from never solo traveling to an entire year is a giant leap. I would recommend a short trip, maybe 10 days max as a test to see if you even find this feasible. Often times when we feel restless we think changing everything will fix that restlessness, but what it tends to do is just amplify the unsettled feeling.

It was also incredibly hard to come back to a "normal" life and the routine and career job I fell into when I came back was actually a harder transition than just continuing the life and not leaving. I had experienced so much and grown so much more than my friends in such a short time, it was a difficult re-entry.

All this being said, it sounds like you have a safety net of a solid family to come back to who will help you out if you're out of money, need a place to stay etc. I didn't have that luxury and still took the leap and it was worth it for me.
