do you have a hard time letting go of bad past events?

Yes and no...

Yes. They will always be in my mind but I'm not always aware of them. They are a part of who I am, I learn from pain. Over time I have learned to cope with the pain, I will never forget them, I just have to accept them and I try to.

Yes. It's taken me years to get over some things. I might be getting better at it these days, but I don't want to test that.

[c=#BF0080]Yes.. I dwell on them thinking about what I could have done to make that situation not happen.[/c]

Yes. I seem to have lost my sanity along with it.

depends on the event

Sometimes.
