Parents suppressing the teaching I love my parents, but for some reason they do not understand my teaching and misinterpret what I say and won't listen to me. Their misinterpretations led them to take all of my books on Buddhism I was studying as well as prevent me from meditation whenever I try or try to be mindful of doing anything, they prevent me from having to do with the Buddha's teachings (However, I can still do online things in secret as you can see). They say that when I leave the house or grow to a sufficient age, then I can resume, but for now, they have the right to take away my religion basically and it is really putting a hard toll on my spiritual growth and practice for purity. They hope it will fade away, but I have used the Dhamma as my practice for two years now and I have grown to know its truth, unlike my parents.

Does anyone have any recommendations on what I should do? Are there
any ways I can continue the practice even though my parents work
effortlessly for me not to do so? How can I work to show metta to them
when I want to but get frustrations when they push away my teachings
or speak as if Buddhism is a "cult" that makes me anti-social and a
bad person, even though I have explained all of it to them?

Please help! Metta!
You should not be teaching your parents Buddhism. It is forbidden in Buddhism to teach others Buddhism; unless the other people request to be taught (AN 9.5). 

You should not be practising "zombie mindfulness" in sight of your parents because this will freak them out. As a Buddhist, your practise is to not cause harm or distress to others. In your parent's home, when with others, you should act naturally and normally. 

Apart from this, there is nothing stopping you from meditating in private and also practising right speech, right action &amp; right livelihood in public. 

Buddhism (DN 31) says your parents have the duty to train you for a profession, i.e., ensure you receive an education. Your Buddhism should not interfere with your schooling and education.
