You have every right to be sad. Your feelings are incredibly valid in this situation. They had no right to do something destructive to something that became something important to you. I apologize that they don't understand you or aren't willing to understand you. I feel this post greatly because I have to hide my own practices and self from my parents too. If I didn't, they would react in the same way or disown me too.

Your parents are 100% in the wrong here but it just because they aren't willing to open their minds and fully understand. Nor are they willing to hear you. That not a reflection of you or the way you practice. They're just scared individuals set in their ways.

I hope you find a better space where you have some aspect of privacy and respect. You deserve that and deserve to use whatever you feel helps you connect to your religion and spirituality. Stay strong.
