Sensory issues….

Advice please?? I have ADHD, am newly pregnant, and have a toddler. I did really well with sensory stuff before, but since getting pregnant, I’m really struggling. I hit a point at the end of each day where I just don’t want to be touched, talked to, or around others. I want to sit in a dark room by myself. Sometimes I just want to scream! I feel so bad too. My daughter is a huge mommy’s girl and very touchy. Which I LOVE! But it gets really overwhelming by the end of the day when she won’t even acknowledge my husband as she is climbing all over me… she’s only 20 months….any advice on what I can do??? Thank you(:
