I HATE FINITE MATH

I'm going insane. I moved to online school after the first semester and now have to take a math class because the state waiver doesn't apply to online classes. They put me in finite. I'm starting at the beginning but this is the most challenging "math" I've ever done. I cry every time I do my assignments because I just don't understand. Half the time I have to have my older sister explain it to me(she's a math teacher) and the other half I just use chatGPT. But like I need to understand it so I can do well on my tests. Truth tables are the bane of my existence. If this then that, if not this then that, if not this then not that, if not that then not then.. and then they add "r" to the growing list of symbols and ps and as and it's TOO MUCH. WHAT THE FUCK
