I just want to say, I think you're doing great to weight all the option. These are really nice options and wish that you will succeed in any of them.
Just one idea, maybe you can enlist a psychologist to help you reach a decision, and incidentally you can use the opportunity to discuss and learn more about a potential career in psychology.
Good luck again!
Oh and about degrees being recognized, it would be an issue if you want to pursue education abroad. You can probably find the information online. Maybe on this site for Germany:

For work it is not such an issue, most employers just look and see that you have a degree.
Of course if you're in a medical profession, you need a license, and that's something else.
And one more thing, about "establishing your life and fast", in my experience, it didn't work well, It just got me to a place I didn't want to be, with little motivation left. Shortcuts hardly work, you don't want to be taking shortcuts in your life, you're worth more then that. Also chasing the money doesn't work that well in my opinion.
The reason being that you would end up doing things that do not interest or motivate you that much, and "chasing the money" or even "getting established" are vague and elusive goals. I believe it brings better success to have a clear and concrete goal.
