I hadn't cried in 7 years and decided to do some emotional exercises to make myself cry. So I managed to cry about 4 months ago, haven't been able to since even with my grandmothers death. Might start trying again.
I like that exercise actors do where they watch a clip that made them cry in the past. That scene whwre Dr. Gregory House indirectly saves the quadraplegic with single shot of cortisol gets me every time. Such a soft spot for those who heal and are healed.
