Echo recommendation for CBT. Helped me greatly and it will help you.

How old will you be in 5 years if you do nothing? 45. If you make big changes, how old will you be in 5 years? The same? The point is: your age has nothing to do with it. At 40, you're still young.

Get thee back to the US. You can change careers.

You can have a wife and kids. Although be prepared to meet women with "baggage" - a prior divorce and children. The key to find a wife is to treat it like a second full-time job. Were you raised in a particular religious faith? If yes, join a singles group associated to it? Worried that you'll meet a woman who will want to go to church every Sunday? Stop worrying -- you can sit through anything for an hour.

You're not too old. It's not too late.

Good luck.
