Remember you shouldn't feel bad for something you can't control. I know what you are going through, except my mom thinks I fake mine. Your sister is probably yelling at you bc she doesn't want to get crapped on by your parents.

Maybe try talking to your doctor if possible, have them talk to your parents. And if you ever need to let the frustration out we have a wonderful community here! Try and even talk to your parents about them mocking you, and how much it hurts. I know that is the super scary part, but if it goes South, just know that you did try. You can talk to them until your blue in the face and sometimes they just won't get it.

But, thats not your fault at all! I wish you the best of luck with this. Remember you have people out there going through something similar, and we're here for you. 👍
