I feel like a hostage to my toddler

Let me start by saying that my daughter is 19 months and severely speech delayed, so I know that has a big impact on why she is the way she is.She screams ALL THE TIME. If I am not sitting down WITH her, she screams. I can't get anything done, ever. She will scream for hours. It makes nearly every outing, every minute of my life miserable. I hate feeling this way, I think I'm starting to resent her. Everything in my life is catering to "Please, stop screaming."She screams in her high chair. She screams in the car seat. She screams in the living room if I have to go to the bathroom. She screams while I'm making dinner. She screams while I'm trying to help my 7 year old with his homework. I took her to one of my doctors appointments and she screamed to the point where I broke down crying in the room. Grocery store? Screams. Park? Screams. Play date? Screams.And not just crying. I'm talking guttural, primal screaming. The kind that vibrates your ear drums. The kind every parent hears once in a while and has to take a step back because, woah, kid. Except I hear it all day, every single day.My poor son... I know he feels somewhat abandoned. Anything he wants to do has to be put off until his sister goes to sleep at night. Taking him for a bike ride? Out of the question; his sister will scream because she wants to run into the road. Doing his homework entails sitting his sister in her high chair with snacks and elmo, him trying to concentrate while she screams and me going back and forth from, "sissy, look what Elmo's doing please stop screaming" and "okay, so they want you figure out how much money Sam has"I would love to think that this is a phase, that it will pass someday. But it's been like this since she was born. 19 months of hardcore daily screaming. And it's not tantrums... It's like her default mode.She has my attention all day, everyday. I don't know how much longer I can do this.I feel like I did this to her. My pregnancy with her coincided with the most stressful time of my life and I didn't really bond with the baby inside me. But by the time she was born things were ok and I was ok. I have a therapist that I like but in all honesty, I just don't really feel like it works for me. Everything she says to me is something I've already thought to myself, and I do have a pretty good support system that I talk to regularly.I guess I just needed to vent more. I'm just at a total loss. via /r/Parenting http://ift.tt/2dYWCEb
