I know it varies from person to person, but some trauma that happens does need to be acknowledged and then moved past.

An elderly pet dying? Yeah, that is just an inevitable part of life and can be traumatic but eventually there is a need to move past it. Even a surprise death from a young pet needs to eventually be dealt with, because that kind of thing happens. Therapy shouldn’t really be needed for things that are just part of how the world works, but sometimes it is.

Sexual abuse or a parent dying in a tragic accident? There should not be an expectation that someone ‘just moves past it’.
