Is something wrong with me?

Okay, so a family member of my passed away last night, unfortunately. When I tell I did not shed a single fucking tear for them, I am not lying. And I’m concerned because this person LIVED with me. I saw them EVERYDAY. They were mentally and physically disabled so sometimes I even fed them. Y’know? I cried for like, I kid you not, 10 SECONDS?? And that was only because I saw my dad crying and that shit made me KIND OF sad. I feel so unbothered that it’s freaking me out and I feel ashamed(?) because it just feels rude not crying. I don’t want to admit that it might be because I was not as emotionally attached to this person as everyone else. I feel out of place. I did get a headache when I passed the body but that’s all. I refused to see their corpse too because I don’t want anyone to see how nonchalant and unsympathetic I am.
