I'm Upset Because Life Didn't Turn Out How It's Meant To Be?

I'm nearly 30 years old. My twenties wasn't the best time of my life. I'm upset because I didn't do a lot of things I was meant to do in my twenties. I dropped out of university, didn't learn how to drive, I was so broke and couldn't afford many things. I didn't go on holiday and so forth. Low self esteem is the reason why I achieved nothing in my twenties. If life went okay for me, I could have got a car, had an iphone and not repaying debt. Right now I'm repaying debt and have a bad credit history. For the rest of my life, I'm going to feel sad for not achieving anything in my twenties. When I see young women being happy in their twenties, I get jealous. What can I do?

How to have an online relationship?

So I've been talking to this guy on kik (instant message app for iphone) for over 2 months now, and we really like each other. We've told each other how we feel but now its kind of awkward because were not really in a relationship? Because we live in different countries and its unlikely that we'll get to see each other. But still, its kind of like we're in a relationship because we kinda stopped seeing other people, only we don't do the things usual couples do. So what should I do? Should i start calling us boyfriend and girlfriend? And how would that work, I've never done this before so I have no idea. I'd really appreciate any advice.
Ps: we've sent i've pictures of each other and we skyped once, so don't tell me too be careful, because i don't know if hes some 70 year old pedo, etc etc
