Father passed away

Father passed away there after a struggle with cancer.
I’m still in it, but how few people have contacted me to send condolences is mental. Is it cause I’m not on Facebook?
The people I work with, most of whom I have never even met in real life, sent the nicest messages.
My team has a great culture the kinda sucks people into it, it’s nice.
I’m still in it, and I guess this is my outlet for self indulgence…
