_Wow, that sounds really really frustrating. From that bit about her being stuc in bed and in the house for the last couple years, it seems to me that shes going stir crazy and venting it out. You unfortunately, seem to be the one shes singled out as the scape goat of her frustrations. Have you tried giving her some small things to do? Like maybe...embroidery or video games ornew books to read? I know they aren't overly exciting, or suiting if your mom isnt into video games or stuff like that, but i guess its a start. Or maybe sit down and talk to her about it, on how its making you feel when she yells at you for little things and come up with ideas with her on what you can both do to help the situation?

_Sorry if it doesn't help, and good luck with your mom!
