As most people wake up from a serious illness or event, I suppose family and friends supporting you would be an immediate comfort. They would tell you the basics of what your life has been like although they might take advantage of this to change you. I would probably look all around places I’ve been before my whole life and see if what I see now corresponds to what I used to see in hopes that I might remember and glean some information about life before the mysterious falling object. Places like my home and schools are primarily what I’ve spent most of my life in and so I would search these areas first.
The emotional part of the journey might come after remembering everything since if everything was forgotten, everything would be foreign. As the journey begins, probably frustration and confusion for things people expect you to know but you can’t bring yourself to recall. Afterwards, there might be a sense of deja vu when seeing places that were familiar or some sense of nostalgia.
I think I would try to remember as much as possible from the incident as all the experiences I’ve had shaped me into who I am. To not remember negative experiences for connivence sounds a lot like running away from who you are. If you wanted to change yourself, you should do it consciously rather than use some lame excuse like (retrograde) amnesia.
