I Want My Girlfriend to STOP

I am so sick of my girlfriend right now. I have a problem with seizures and she knows this. We've been together for almost a year. About a month ago I had a really bad one and pooped myself. I know okay. It's childish and embarrassing. I thought she would be more understanding but she laughs about it and has told all her friends and family about the time her boyfriend shit himself at Target.... Maybe I'm overreacting but we were hanging out with my co-worker. Just having some beer. Even my boss stopped by and she decided to tell them about me pooping my pants during a fucking SEIZURE! I've told her multiple times it embarrasses me but she's like they are laughing with you not at you. I'm not laughing so it sure feels like it's at me...
