I think that really depends on the internship. In most cases, it is false that working for a big company will be "nothing more" than a nice line on your resume. I've interned at both startups and big corporations, and learned an enormous amount at both kinds of companies.
frankly, your description is deceptive or you're deceiving youself.
From your own description, you're spending all your time at work and you're obsessed with that problem.
1/ you're not married. You're just the ghost of lovers. being married means something like enjoying spending time with your precious other.
2/ you're not travelling : you're moving from one airport to the other, with a brief pause in office and hotel between them. travelling means learning the country you're in. Don't delude yourself, you're not travelling except on the surface.
3/ you have no friends, as the rest you have no time for them.
I know the pull of a (code) project, especially when you're the boss. It can become an obsession, and eat over your personnal life.
But believe me, beyond 9 hours of real work, you're worthless. Many excellent, brillant coders underlined that for men and in the end, I have to admit they are right.
