The one with the reason

The only reason I decided to celebtrate Christmas and my birthday all alone is because I knew there was a decision that I needed to make. This would probebly be the hardest decision that I had to make in my entire life thus far. Like it or not, I had to make a choice. The problem is, I have already made choice, and today upon execution, it feels like the worse decision that I have ever made. The only problem is that I know that the decision that I made is the right one, if not for now, for the long run. How do I know it is right...??? Because it feels so wrong...
