Frankly, I don't think it would change anything. I've tried several life changes in the past to flee from my fears: go on a pilgrimage, move to a different country and study there and take up some odd jobs.
Nothing changed my inner outlook on the long term. At first I felt a little bit better because I thought I had finally changed my life for the better, but my problems always caught up to me, sooner or later.

"If I was incredibly rich, everything would be so much easier" sounds like one of those escape fantasies I fled into so many times to no avail. There is an upper limit to the amount of money that makes us happier. Above that limit, more money doesn't mean more happiness.
And to arrive at the goal so many people in society have, "being rich and famous", yet still miserable? That sounds like an utter nightmare to me, to know that you're "living the dream" and still aren't as content as the average guy.
