How do I learn to quit fearing the unknown?

Actually, it can be really easy, first, you should learn what that unknown is. Once you study and understand , it wont be so scary anymore.

It's best to teach yourself to live in the now. As cliche as that may seem, having anxiety myself can really drive me up the wall, but keeping yourself occupied will really help.

By understanding that the unknown will be unknown regardless. Life is so much easier when you stop worrying so much about what's out your control. Honestly, try it!

Come in touch with things you don't know bit by bit. Or do research, think on it and be amazed. Try not to be afraid of the uknown.

I believe in exposure therapy, which is a technique used in behavioral therapy. If we are exposed to what we are afraid, in a safe setting in which outcomes can be controlled, we have the opportunity to develop ways of coping with what trigger our fears. By facing it, we learn that there are methods to reduce the anxiety it causes, and eventually overcoming the fear all together. It may be difficult in the beginning, however as we attempt multiple times, we not only gain confidence but begin to believe in our own willpower.

Facing the unknown with a bit a of courage can be of immense help. Facing the unknown helps one combat the fear factor.

Draw strength from all the times you have gone into the unknown and survived; educate yourself so you know a little more about the unknown thing; talk to people about your fears and hear how they have overcome theirs and develop strategies to help support you - but ultimately dig deep and dive in with courage, knowing you've conquered 'unknown' before, you're not the only one, you're prepared and you have ways to support yourself if the 'unknown' turns out to be tougher than you thought.

When you can stop living in anticipation of the future & honor the here and now, this present moment is all there ever is, or is it not?

You have to find courage. You can ask someone you trust to do this new thing with you or at least stand by your side.

It is normal to fear the unknown, be it a new school, a new job or a different environment. The thing is, you'll get used to the new situation, so over thinking won't get you anywhere. Doing something you really like, or going to a familiar place could also help. Change is good, and fear of unknown is normal.
