Depressing thoughts and 'What am I doing with my life'

So this morning I booked my flights. I’ll spend at least a month in Bali, and another month in Bangkok, then I’ll see if i stay longer in one of those places or keep traveling. I feel weird about it. Even though on the one hand I can’t wait for this new adventure and I’m getting super excited thinking about it, it also makes me really nervous and even a bit depressed. I got thoughts popping up in my head like- Is this the right decision? Am I just running away from the real world?
