Nah, not really. There are some things I think about occasionally that I seem to have very little control over, like when my PTSD is triggered from being physically, mentally, and emotionally abused as a little guy, or when my pet died but I think about the good times with my pet and that makes it better. With the rest I make sure to toughen up about and move on quickly as possible. I force myself to get over it. I don't believe in living in the past sadness, not only do I feel bad but I make other people around me feel bad by being that way. Most people don't want to be around someone like that who's always depressed and depressing.
