You really need to open your eyes to the bigger picture here instead of just living your life trying to please your parents while your own life is destroying you. How long will it be before they are dead an you can claim your freedom? You only have one life, there is no point in wasting it trying to please others in a cult where nothing you do is ever really good enough anyway. That is such a wasted life.
I was going to say something like this too
You are responsible for your own life and your own happiness. Nothing more and nothing less. Your parents are responsible for their own happiness. Not you.
That being said, welcome here! Don't let some of our stronger opinions discourage you! After all, your choices are yours to make, without our judgment (and without any medling JW judgment and gossip!)
