teasing - help please

Quite simply, this is like the childhood bully. My husband and oldest daughter (a doctor!) brush off putting me down for my migraine as "oh we were just teasing". And they are mean. "You don't do anything, you are useless, etc, you are whiney, you just want to get out of doing anything". When I tell them to stop, its either gaslighting with we never said that or "oh we were just teasing". Any suggestions on how to make them stop. My youngest son is the only one that helps with a box of crackers and 7up. I don't want to be around them anymore, it makes me so sad. My husband stubs his toe and we are all on high alert to change his bandages, put a pillow under his foot, etc. Help. I don't want to be in this family any more. I'm getting severe depression.
