No reason to make up to anyone, your well being is the important thing at this present time, and I personally do not see a need for you to apologize, okay?
You take some time, treat yourself to something, free time to just relax, or whatever would be fun for you.

PS also know that you are welcome to return anytime.
Please take care now,
