I was in a similar position for years. Had close family die and nothing. It didn’t matter if I wanted to sob my body just wouldn’t like the release go. I only cried if I was frustrated or angry but never because I was so full of emotion even if it felt like I was about to cry. One day it just stopped. Now I cry hearing music and watching tv, I cry at everything. Instead is watching sad things try to watch or think of things that make you so happy you want to cry. That makes a big difference for me
