First Time Self Haircut

I live in a white dominant state and no barbers here can cut my hair , so I had to say "Fine , I'll do it myself." How bad did I chop myself? Is there any advice you guys could give me ? I'm trying to not be hard on myself. I meant to do a low taper but I messed up and I think I started overcutting it. I want to learn how to cut my own hair but I get discouraged VERY easily, especially trying new things. I know practice makes perfect, and for the first time I definitely didn't expect it to look good. Anything I could try differently? Do I just keep practicing cutting my hair and watching tutorials? I'm a visual learner I need someone in person right next to me telling me what to do or else I won't get it 😭 thanks
