I am really fed up with my family. My mom and sister have lots of chronic illnesses. My mom has MS, high blood pressure and cholesterol and chronic skin problems and had cancer previously and my sister has POTS, endometriosis, epilepsy, ADHD, anxiety and more and has had appendicitis. It is really annoying because life has to constantly revolve around them making sure they are ok and I am really getting sick of it now. I have snapped at both of them quite a few times. My dad isn't very helpful about it all he says is just be glad you don't have any of it which makes me so made. They are my family but it is doing my head in now and I am fed up of having to be strong and this isn't a conversation I feel able to have with them about how I feel. I feel like I am expected to be the healthy one. What can I do?
