Solo Travel Blues: What to do?

I'm having a meltdown because I just realized that I'll be travelling to another country alone this December. I feel scared and anxious, which is why, I just realized, di ko pa actually na p-plan yung gagawin ko sa Vietnam. I'm usually happy and excited by the idea, but now that I think about it, I'm scared. But it is my dream to travel alone! I swear. I just have to get over this, and I'll be good to go.

How was it for you when you planned your first international solo trip? Ako lang ba to? Hahaha
