I am fully aware of 'tiger mothers'. My roommate is from Taiwan and she has a lot of pressure from her family to do well. Her whole psyche is built around pleasing her family and doing well. Her parents and older siblings have all been fairly successful in their careers. (They are 8-10 years older than her)
Even if you feel like you cannot see a therapist, there are still some holistic ways that may help you. You can try looking up mindful meditation, (Or any type of meditation!) and trying to find free resources online (Like there are some CBT/DBT exercises). Adding some exercise may also help you. Being active here and talking to people about some of your emotions can also help.
I can't gauge how severe the symptoms you have. Moving away from your family may be the key in your ability to really recover. Can you talk to your dad? Your mom doesn't sound emotionally stable, but maybe your dad is? You might be able to talk to him and have him help you out somehow.
I don't think you are lazy. It sounds like you are stressed out about your home life and it is making it hard for you to cope outside of it. I wish I could help more.
