I remeber when my uncle died a few years ago. And my uncles son was 17 at the tiome. few years later told me that he couldn't cry at the time and didn't. because of this he almost came to the point of suicide. He said that I was so guilty and ashamed that my father died and I didn't cry. he didn't commit suicide but said 4-5 years later on he cried till he couldn't no more. Now he's come to the realisation that he just couldn't show his emotions and just supressed them at the time. buit he did feel sorrow and grief just that people deal with it differently. I know I also welled up when I visited his grave like 5 years on. but just cos you dont cry dont mean that you aint feeling nothing for the person.
