I made a plan with my friends for traveling. I really wanted to go and was looking for tickets and stuff and finally the plan was made and now I'm supposed to go in a few days. However, once the plan was finalized... I started to doubt my decision.

Was it the best decision?
Should I really go?
What if something bad happens?
What if my friends betray me? (ik it sounds mean and i feel bad for thinking that but my brain just throws these thoughts)
What if the trip is a mistake?

I think of all the bad stuff that can happen and it just totally tanks my mood.

Is this a symptom of anxiety? Am I suffering from anxiety? My palms are sweaty as I type this.

Has anyone ever felt this kind of stuff?
