Every time a friend comes home from traveling, their first question to is always, “How do you cope with post-travel depression?”
There is no real cure for the post-trip blues. The only real way to get over post-trip depressions is to stay busy. You talk people online, go to meet-ups, or plan your next trip. Keep that energy you had on the road going. Go out, sightsee in your own town, take road trips, find a hobby… do something. Because the more you stay still, the worse your depression will be.
But it only ever fades as more time passes. There’s no cure other than time. It’s like getting over a relationship. Sure, you can stay busy but it’s only as time progresses that you slowly begin to move on.
When you were traveling, you viewed every moment as an adventure. View your life back home as one too. Stay busy. Stay active. Try new things. Keep that can do attitude.
When you do that, home will feel a little less suffocating.
