Am I being selfish ?

Stephanie • First time being pregnant & im having a boy !💙👶🏼
Sorry it's kind of long but I need some advice , so I'm due November 20th and my baby shower date was for September 26th. I had the invites and everything made already but 2 weeks ago my step dads mom got diagnosed with pancreatic cancer . They only gave her a month to live so I decided to push my baby shower date till October 10th. Well after having a talk with my mom and step dad last night they think it's best that I don't have a baby shower because of what's going on . I feel that's not right because this is my first child and I think I should have a baby shower . Am I being selfish?
