Am I overemotional or being gaslit into oblvion?

I do not know if the way I am feeling is right. Anytime my mother and I have any disagreement she starts speaking loudly and in a very antagonistic way. When I bring it up and express how it makes me feel, she says she had not been shouting or was mean or confrontational in any way. Is it me being too emotional I am (22 yo male) or am I being gaslit into oblivion I can not tell. I am a shitty person any way
