Did you have surgery with any kind of anesthesia as a result of your injuries? Or any other heavy duty meds? Sometimes those on top of stress and trauma can alter you for a while.

what about: you had a very bad experience and are feeling down. takes a while till you are back on track.

Has the fear of dying left you? If so, it's likely left a large void that you will now have to proactively and purposefully fill with more positive emotions.

it really makes some sense.
if you died in other realityes,part of your counsuisness is lost,if we are all a part of it.
and im glad you lived^^

You're probably in a state of shock or something.

There's no such thing as "should have died."

Many of us have almost died, myself included.
