Yup. Every so often it is important to get some rest and get your strength back so you don't burn out - and take this from someone with first hand experience, you can't really help people when you're burned out.
I'll be okay in the meantime. Just focus on getting your strength back.
I'm pretty good though already. Most I can say is my voice is really weak and my ears are plugged up, but the coughing and sneezing that have been making my life miserable the past couple days have been subsiding a lot today. I will continue to rest, but I'm making a nice recovery already.
