<human>: All my life I have been shy, and have never had a girlfriend nor have I tried to ask someone out. But I really like this girl and have decided that I don't want to have anything to regret, so I'm going to at least try to ask her out.  She is average looking, as am I, but I'm not a very outgoing person.  I've thought a lot about her rejecting me, or me embarrassing myself if she says no, but I think it might work.

We used to be friends a couple of years ago, but we just stopped talking for no reason.  We live in the same town and went to the same school for a long time, but now we go to different high schools.

How do I ask her out? Should I message her on Facebook, or wait for the unlikely event that I will see her in person?  Also, is it even worth it now, or should I just wait until i'm older to have a relationship with someone?

Can you provide a brief rundown of the text in within 3 sentences?
