((((((((((((Jennifer))))))))))) I'm sorry you are struggling right now. Do you have any friends that might allow you to spend a night here and there to break up the time spent at home with parents? Are you getting disability that you can use toward getting a place by yourself to live?
I just got done with a visit from parents here and it completely rocked my world. I am struggling to come back to the present even as we speak. I couldn't live with parents so I understand the stress you must be feeling right now.
I think writing is a great idea if you can do it. It helps for me to get things out of my brain. Sometimes I cling to my journal to stay alive.
Please do what you can to stay safe. And let us know how you are doing when you have time.
Take care.
