Can I have no emotions?

So my mom gets pissed of at me because when she yells at me, I don't yell back regardless of what she is saying, I don't get pissed I try to stay calm and figure things out. She thinks i don't have a heart or show emotions, because she does some really cruel things to me, and instead of getting pissed i just solve the issues she causes for me. This has gone on my whole life, but I vaguely remember when i was a kid that i would try really hard not to show emotions when i'm sad or mad, because it serves no purpose. Is it possible that i become immune to these emotions? Should i just fake emotions just to make her happy? Or what?
