why am i so unimportant to everyone

had to get my lymph nodes checked today because i have a lump that wont go away. my family knows about it and honestly yes i was scared shitless but i tried not to show it and thankfully the doc said for now it looks fine. none of my family members asked how my appointment went today even though they knew i went there. such a stupid thing to be mad over i know. i just don't understand why it is so hard for them to care about me when all i do is run around and help them and listen to them
