Is it okay if I bail on a date?
Why are you bailing?
Because I don't want to go out with them
It is okay not to want to be in a situation but you should let them know what you don't want to be there. Otherwise you will make people worry.
Don't stress me like that. I should be able to do what I want.
If you made a commitment then you should at minimum inform the other party that you no longer will be attending. If not they'll end up wasting their time showing up for your date and would be embarrassed when you don't show up. They might be led to believe they did something wrong.
