Go for it - after ensuring you have what you need to come back to - but don't put too much stock in the "life-changing" part. We are who we are and travel is just what it is. The epiphanies come or they don't. I don't think there is anything magical, per se about travel.
That said, moving out of the hum drum of one's normal everyday life is always VERY good for me. Actually, I don't think it is the travel that prompts me to new understandings as much as it is moving out of the orbit of things and people that become too demanding, suck too much out of me - because I allow them to. When I head off on a trip it's like I can breathe again.
I don't feel that as much now, but a few years ago I was in a job that was sucking the life out of me, a famly member was presenting as an overwhelming emotional burden and I had two teenage sons with all the worry they bring.
So I'd head off on a trip and within a two-three days this big load would lift off my shoulders. My husband would say, "Don't call home." But eventually I would and then for a day or two the burden would settle back on ....until enough days passed and it evaporated.
Now, I quit the job, the parent is dead and the boys are adults with stable lives. So when I head off on a trip it's just a trip. My life is so much less stressful that travel does not present that contrast. I don't NEED that open space in my life to re-think my life.
So will travel be life-changing for you? Only time will tell but don't expect too much magic our you will be disappointed.
