I found a kid having his football ball stuck on a high place and he was to small to get it. I came to help him but while helping I saw that the ball had Christian symbols on it. I had a thought that maybe I shouldn't help him, as maybe it is kufr but did it anyway due to shyness. Is it kufr ?

It is waswas and you should seek medical help in sha'a Allah.
