How do you cope up with the debt and living abroad?

I am 29 years old, about to be 30 in a month. Moved to Europe when I was 24, where culture is different from my home land. Had to learn new language from scratch , still working on it. Since i arrived in New country, i was suffering chronic leg pain of extreme type, which hindered my mental ability, hence it took me 6 years to finish my master studies. I have never had a girlfriend due cultural reasons, chronic pain and low self confidence. I had to borrow some money from friends, when i was unable to walk or stand. Currently, the total debt is around 22k € /~$ 21k . Now that I'm relieved from chronic pain, i suddenly feel, 'what have i don't to my life?' !. Do I i stand a chance to get back? How do i do it? I'm a mechanical engineer who who aspired to start my business some day and have a girl friend, uphold my family financial problems, etc. Your ideas, suggestions and plans are appreciated . Thanks
