I "dwell" only to understand, although after being mentally abused for years. I noticed a tendency to recall bad experiences and feel fear over specific certain social situations. It's really stupid when coupled with a nervousness around new people. The recall and feelings of dread, shame, guilt, and worthlessness are annoying. Although, I've come to control those thoughts better.
What I mostly have is regret and anger and unresolved issues of justice. I'm thinking political activism might be the only road to satiate the need for justice and coupled with my talents it's probably a good road to work through some unresolved feelings.
A good year or two of strong personal growth, and I'll be back to where I was before the abuse.
