I have not cried since my father died and I don’t feel anything

I have not cried since my father died, I’m still in shock, it has been years and I know there is a pain inside but doesn’t come out. Maybe because they left me in poor financial condition and I’m working hard day and night to bring my self up financially. I was an emotional person who used to feel for other people but now when I see others in pain or seeing them in very tragic situation I don’t feel anything for them at all. I don’t have friends so this is the first time I’m sharing this. Has anyone had this similar experience?
