What should I do? I'm afraid to go outside.
Is there a particular reason that you don't want to go outside?
I am not sure. The only place that seems exciting to go to would be a resort.
The place you want to go sounds great and I think you should confront your fears and go. Being outside shouldn't be something that you're afraid of and once you make that leap it will get easier and easier.
Hiding from the outside world makes me feel like I am going to die.
It's understandable that you have developed some anxiety about going outdoors after being inside for some time. However, you should take the first step by stepping outside for a few minutes.
