nervous

Now that I'm certain that I'm going to Paredes de Coura I'm starting to feel really anxious.
I wanted to go for years and this is the year that I'll finally be able to.
But now the axiety starts: "what if I don't like?", " what if I'll just be so unconfortable that I want enjoy it at all?", "I'm not rich and I really could use the many, is it worth it?"
I was so certain of it but now... now I'm just full of doubts.
