I'm so sorry that you felt that way. It's hard dealing with really negative feelings that consistently bring you down. Those feelings are difficult to fight off and ward off. It's like these emotions are tearing those walls down and taking over me. It's painful
I'm sorry that you're having to feel so overwhelmed with so much responsibilities as a parent and having to try and cope with these heavy emotions as well.
Have you tried asking a friend or a neighbor to look after your child for a little bit while you try and calm down? I believe there are certain volunteer services that help out with child care as well, especially for children with disabilities.
I hope your day will be better, and there are those tough days that seem to never end. But don't lose hop!
