It's nice that you have a workplace that cares about you for what you are, not just the value you produce.
We wish that was the case with our work- we have to show up for shifts even if we have a fever. Sometimes we feel like we are soldiers in the military with this work that we have.

We admit that we are a bit jealous, but than again we also understand that this might not be appropriate- because we don't read that you're happy to be treated with consideration. We hear that you are embarrassed. That you feel that this is something bad that happen. We don't think it's a bad thing that happen- to show up sick for work (which deserves kudos in our book) & to be sent home for rest & recovery.
It's not like you choose to be too sick to work.But if it happened to us we might have feel the same. Also, we don't want to sound intrusive or invasive. We just read carefully & try to pay attention as we're also pre-occupied with work related issues.
