My family just doesn't understand.
My family has suffered a lot of tragedies, my dad was just diagnosed with cancer, my sister is severely disabled and my other sister passed away from cancer. I'm the oldest and under extreme amounts of pressure in my life. I'm aspiring to get into med school in the next couple years, but on top of that I have to take responsibility and be an adult to care for my disabled sister. My parents do not understand the amount of stress it causes me that her life will depend on me caring for her sooner or later. I love her to death, but I'm only 19 and I feel like I'm growing up too fast. It's becoming too difficult to balance school with friends that I rarely see, with family responsibilities and a job. Sometimes I wish my parents would cut me some slack and try to imagine life from my perspective, but instead they frequently get mad and frustrated with/at me. What should I do
Is this normal?
