I am a revert to Shia Islam from (removed). My parents somehow consider mourning on the day of ashura is haram and an innovation. I am obligated to be in taqiya because of this and never disclosed my faith to them or anyone in my family. Tomorrow is Ashura for me, can you advice me what all I can do and the things I should avoid.

Then stay at home to avoid the conflict.This is the beginning In’Sha’Allah issues will be resolved have strong faith in Allah and submit your affairs to Him and pray to Him to help you and guide your parents also. Listen Majalis from iPad and mobile and remember Imam Husain as and mourn for him and get courage and inspiration from Karbala.
In’Sha’Allah things will be resolved and in near future you will be able to practice freely and openly.
