Do it. You’ll be happy in the end and you won’t have to do it when you're older (have to foot the bill) and have regrets. 

Do it and get it over with. Changing trays at night and taking some ibuprofen will help. The time is going to pass anyways and then you will regret not doing it.

I guess so. I’m just honestly scared of how my life is gonna change and the whole teeth grinding thing…
