Does helping others make you upset in a good way ?

I notice that when i help others such as seeing someone who looks hungry or thirsty when i walk into a gas station or someone asking for food & asking them what it is they want and ordering it for them even if it seems like alot unhoused or someone in a time if need i seen on a reddit post and i PM them to help them with alittle amount they may need help with. It really does get to me and not alot gets me i would picture myself as cold hearted, but when it comes to helping other humans i get upset about it after i helped them.

Maybe its because i seen some people help me as a kid when my mom had nothing, or maybe because i just know what its like compeltely to be down and out & needed help and know what its like to be ignored and not have anyone really care & i know what its like to be a stray dog without a family or a wolf cut from the pack. I really dont know why but i know it upsets me and i keep those people in my prayers.
