my parents ... they were sorry too and they told me to move on
Sadly, many people have difficulty providing sympathetic support to someone in crisis, even when it's a member of the family. I'm sorry you received an answer like that, because when we are grieving or feel depressed, we can't "just snap out of it" and "move on".
We need time to deal with the emotions of loss, and with support and sometimes therapy, we can find ways to deal with our depressed mood.
I cannot recall what you told us, Cobra...are you currently being treated for mood disorders separate from the grief you feel for your recent loss?
