I'm 18 years old, and I'm married. I have been for close to 3 months now. If you know you have found the right person for you-Then I wouldn't see a problem. Just be sure to bare in mind, marriage is a huge responsibility. I moved 15 hours to be with my husband. I lived in Virginia,and he lives up here in Wisconsin. One of us had to make the sacrifice, so I did, and I do get homesick often, but overall it was worth it.
I'm sure you'll be fine though, and congrats!!! Telling your parents isn't as bad as what it seems..which you understand now I'm sure. lol I was afraid of telling my folks, because they know it would involve one of us to move. But, they took it well, of course they had their concerns. But, now things are wonderful.
Good luck on your marriage!
