Just stfu please

I hate it when my parents say "let's go out" or "just open your window" like I can't and they know it they know I am chronically ill they know I can't that I don't have enough strength and that I get terrible headaches from light and I'm already grieving my past life and the life u could've had if u was healthy but every time they say something like that and keep repeating it knowing I can't and making me feel bad about myself I can't anymore please make it stop i just want to push past every pain but I can't I just can't
