How does it feel when all you did was to accompany someone, and you got sarcasm in return?

I have the choice to not accompany you, I admit. But at least, don't give me sarcastic messages if I'm doing it for you. It just feels like crap to me. Maybe it's my fault to even do so much.

If you want me to care less, let me know without all those remarks please. If you don't realise, I have feelings too.

Thanks.
