Need help from others who are audhd - how do I make myself study?

I absolutely hate studying, I'll do it for like two days in a row then give up. I was never raised to care about my education and my parents didn't either so I eventually got expelled for missing a ton of school cause of my mental health and just never went back. I'm trying to study for my GED now, I passed the TABE all good. But since then I'm too lazy to study and do the practice tests. I'd rather be watching my cartoons and stuff but I know I have to but I literally can't. How do I do it???
