The audience made me cry because they laughed at my disabled mother who was next to me
That sounds unfair. Why would people laugh at your disabled mother?
That's how it is, people are thrilled when they see someone struggling.
I'm sorry your mom was being made fun of so much, that was so wrong of them to pick fun at the disabled. Instead of crying, you should have stood up to your mom and put these bullies in their place. They got what they wanted by seeing you cry.
What you're saying doesn't matter, only thing that matters is that my mom is still disabled and in pain.
Even though she is in pain, wouldn't you think she's in more pain seeing you hurt as well? I feel like it would be best to take pride in your mom, and stand up for her whenever possible. It will make both you and her more happy and looking forward to life.
