Is it normal to be embarrassed of doing something even if it's good

So there's this kitten in front of my office, the mother doesn't seem to be there, there's another cat with another kitten but this kitten was never given milk by that cat. the kitten just stays cuddled up alone. Nobody went to help, I don't know if somebody is giving it food or not but it looked very weak, doesn't seem to have eaten anything.

So here's the problem, I bought cat food for kittens, but I'm afraid of giving it some in front of everybody. I've always been like this, I feel embarrassed about doing something that nobody else does, even if it's a good thing. I've tasted the consequence of being different and I have a trauma about this, and never want to do anything that nobody else does, I'm sure this is not normal.

Don't worry though, I will go to the office at the break of dawn when nobody is watching and give the kitten some food :), but I'm afraid it will die before that. currently I'm trying to convince myself to JUST FUCKIN DO IT YOU IDIOT.
