I have constantly tried to run away from things, all my life, not travelling so much, like to Europe, but if it is purely running away, it can be harmful, I know it was for me, but only you can determine if you are travelling or running away, no one else can answer that but you. Travelling can be a good thing, and helpful, and reinvigoratiing and help you find the strength to face the next day, the next rough patch, the next whatever you need to face. But I learned that runnign from your past, and fears, and thoughts, may seem comfortable for awhile, but you'd be running away for the rest of your life. You must determine the true reason, look into your heart and soul and you will know what you are doing. I don't mean to sound like a kill-joy, or downer, but I have run and run, and all it did was make things that much harder when I had to face them and look the demons of my past straight in the eye.
I hope you can find out what your true motives are, and I wish you good luck whatever you decide.
Peace, and good luck,
P.S. Don't take what I said as Gospel, I was merely relaying my experience, if it helped all the better. I know you will be able to determine what is best for you, no one else can tell you that, no one.
THe spirit is a fragile thing, easy to break, but not impossible to fix.
