Child with intellectual disability

Anyone raise/raising or knew someone who had a child with intellectual disabilities?

My daughter was diagnosed on Friday with autism, anxiety, and a moderate intellectual disability. I already knew she had anxiety and autism, but I wasn’t expecting the doctor to say intellectual disability. I cried all day Friday. All the dreams I had for her went out the window. She’s our only child. She’s only 4, but I have feeling that she’s going to function like a one year old for the rest of her life. I’m so heart broken for her. I’m so scared she’s going to be treated so differently. She’s the sweetest child I’ve ever met.

I guess my question is, if anyone has experience with children like this, what has your life been like? Will I be changing diapers for the rest of my life? Will I have to bathe her forever? How will I handle her getting a period when she’s older? Will I ever sleep again? Will we spend the rest our lives In therapy? How will I pay for all this therapy?? Will I ever be able to just live again? I love her, but I feel like my life is now over. I feel like I will never stop taking care of her.

Please give some advice.

Edit: Thank you ladies!

Amanda, your sweet baby girl is so adorable!!! 💖
