First and foremost, done is better than perfect, do what you can and do a little everyday. Your parents nag you a lot because they care so ask them for help when you need it. Don’t be so hard on yourself, you can learn to be disciplined by making a plan and sticking to it. You got this! Also, I’m sorry your parents are being so strict- try to ignore them.
