Well I suppose theres a number of possibilities, heres some I can think of:
1. I think there is a multiverse theory that says there are alternate universes for every decision we make, so its possible that by altering your
past, it will create another universe that diverges from your universe at that specific point, however the universe you are currently in will stay the
same. For some reason this one makes the most sense to me, probably because it seems like the most orderly.
2. The universe changes and like you said, who knows what would happen to yourself, perhaps you would gain memories, or perhaps there would be
another you of the current universe, and the present you would be some kind of anomaly.
3. maybe its impossible to contact yourself. Perhaps the timeline is already written out, and your "attempted contact to the past" was already in
the timeline, and since you didn't see yourself from the future when you were younger, no matter what you try, you can't do it, although you might
be able to contact other people.
4. Universe explodes.
