<human>: Can you condense the text into a few key points?

I've wasted about 4 years of my life being a shut-in and suffering from anxiety, they put me on medicines for this and finally after about a year of taking them my life is starting to get better again.

A couple of days ago I've met this really cute and kind girl, and I grew a crush on her and she on me. I have never been in a serious relationship before because I've always felt I was ugly and girls didn't like me, only since two weeks ago I have starting to put this behind me as I've met people (Specifically girls) who have called me hot, cute and so on.

Now here's the thing, this girl lives far away from me, in a complete different country. And I'm willing to put that aside, I really really like her and I want to make her happy. I have no problem with sweet talking to her or making her smile or anything like that. I just have no fucking clue how to really go on in a relationship. 

I'm a real idiot when it comes to the dos and donts, because I already managed to make her feel upset by talking about a friend of mine who is a girl while my crush is on her period.

Well I'm an idiot for sure, and I really don't want to screw this up. Because for the first time since forever I feel everything is finally starting to turn better. And in the time that I've known her she already has made a big impact on my life. (Making me really happy, and making me put even more effort into getting over my anxiety).
<bot>: Wasted years of my life, now ready to start dating/a relationship but no real idea how to handle it.
