It's nearly impossible for me, and if I do somehow it's restrained. I think my brain understands that unleashing the full brunt of my pain would more than likely be fatal to the body. I'm suicidal enough when I'm not acting on impulse. It "keeps me safer" I'm guessing.
Last time I managed to cry was like 6 months after my mom died. Sister died like 6 months after and I never could.
I really need to get back into cutting, it was kind of like crying. But I have to go to extremes at this point for it to actually do very much for me... Which sometimes becomes a real problem to resolve or conceal without a visit to you know where.
