It seems you could excel at one thing if you could choose between the three. Pick one up, get a medium job and then excel. You're no failure, don't worry about that. And yeah, maybe get some perspective working in another country? Not sure what you mean by mentally exhausted (differences between individuals I guess) but your three months inactivity should have reduced that stress. You can't be doing 'no thing' even though you don't work. Take it easy, learn some new stuff, quit habits increasing stress. That kind of things should help I guess.
