Why are most of my coworkers avoiding me when I’m struggling about my dad dying?

So three years ago, we found out that our dad has lung cancer and he’s been fighting. Last week we found out that his cancer gotten worse and it’s terminal. One of the worst news we’ve ever received.
Last week on Friday, I came to work, one of my coworkers (let’s call her Jeanette) hugged me because she knows I’m going through a rough time. I said hi to my other coworker (let’s called her Juliana) but she just ignored me and looked the other way. Then when I walked off, Juliana continued to talk about her amazing weekend. Cold hearted bitch. At least Jeanette cares.

Then I came into the classroom storming in, threw my bad against the wall and sat down. Two of my coworkers (let’s call them Annette and Tamara) didn’t even asked me what was wrong and continued to do what they did. This was before the students came in. The ladies ignored me. I couldn’t believe they’re ignoring me. So five minutes later I was fed up and screaming, “ARE YOU KIDDING ME? Nobody cares that my dad is dying and nobody is even kind enough ask me what’s wrong!! Fuck this!!!” I stormed off to the restroom and then I got called into the admins office.
Somebody must of reported me and I explained what happened and my boss called me out on my childish behavior. She told me she’s sorry that happened but I’m being a damn child and that was uncalled for and of course nobody is talking to me.

I don’t have much family to talk to, my sisters are gone (both deceased) , dad is dying and my mom and I are no longer in speaking terms (long story). Why is everyone avoiding me? People at work don’t care. I’m autistic, 25 and I don’t know how to handle this!
