Dude.. you're not even 18. I promise you that there are so many more opportunities in life than this. Teenage hormones make everything seem incredibly intense because brains are all over the place at that age. It may feel serious right now. It may feel like this is a huge missed opportunity. I can tell you with certainty that it will be a blip in the radar later on.

The future is scary, but it is also exciting. You have so many opportunities available to you. There are so many doors you can open. So many places you can see. So many things you can do, and there are definitely so many people you will meet. However large your high school is, there are going to be significantly more people you encounter if you go to post-secondary. Even if you don't go to post-secondary, take time right now and consider working abroad. At your age, pretty much every single other country will let you get a VISA to work there for several years as part of the youth programs.

It may seem like this is the only girl you've ever clicked with and that you will never click the same way with anyone else again... until you do click that exact way with someone else again. It is probably going to happen to you many times throughout your life. Each time will feel like it is the end all and be all... but then the next time will just as intense when it happens again.

You're totally normal for feeling this way, but as an adult whose gone through the teenage angst, trust that you've got so much more ahead of you and that, while the worry may be pretty consuming, if you dwell on it you're going to miss out on all the great stuff.
