I unfortunately can't tell you how to find a therapist, because I am not from the US, but to the question if it is worth it:
Absolutely! For me it is still one of the best decisions I took in my life and it helped me so much in fighting my my depression and anxiety.
You don't have to be super rich or be a trust-fund baby to travel around the world for months. I find the general estimates for a more frugal world-traveling for a year are $20.000 to $30.000. This is obviously not doable if you really live paycheck to paycheck, but if you have a relatively well-paying job and live very frugal it is not impossible to save this amount of money. Also there is the more irresponsible solution of taking on debt.
Every contract is legally binding in Germany, even verbal contracts or in this case price tags (to some degree).
This seems to be contrary to what I can find. A price tag is not a contract but an "invitatio ad offerendum" so an invitation for the customer to make an offer at the checkout. Then a contract is created when the cashier accepts this price after scanning it and matching it with the price in their system. Therefore it's not the price tag that counts but the price in the cash register. I could be wrong or the law has changed in the last 1-2 years, but I found this information here (sorry they are all in german):

For me it's not like I don't like music, but there are large stretches of time, where I do not care so much for it. I would guess that I haven't actively choosen to hear music for weaks, possibly months, now. Obviously excluding the music you can't avoid, like background music in movies and video games etc.
I absolutely agree when the person has an incurable physical illness, but I'm unsure where to draw the boundary for people with psychological illnesses.

It is somehow my goto "comfort"-movie
Nice idea, I think a webpage collecting this information to create a top 50 would be really interesting. One question: Where did you find your used ranking of the World Hapiness Report, I found this page but this seems different, eg. Israel is on the 4th place.
I was looking it up to see how it looks like for germany, and according to the data I found it would be on the same rank as Australia:
WHR 16
HDI 4
DI 14
GPI 17
WPFI 21
Sum: 72
As this is such a simple way to do it though, these minor points between the top countries do not mean anything. All these countries are safe choices.
Yeah, sure. I think it's more of an interesting and fun exercise but should not be taken too seriously.
Futurama, Scrubs but if it counts, then number 1 would be the first 6 or so seasons of The Simpsons.
