I find it difficult to learn on my own and not in a physical classroom. I feel very inferior as a person.
Why do you think you have trouble learning that way?
I have ADD, and have never had any luck with school.
Maybe you should get help with learning. If you want to do better in school that will help you a lot.
I can't take tutoring. I've tried before, but I don't like people telling me what to do.
Tutoring is not about making you do things that you don't want to do. It can help you with your learning issues, if you will allow a teacher to support you in your process.
