I can see when time travelers come to our timeline, and where.
If you wanna find them, i think your best chance is to go there and wait
for them, and see if you can see them come in. They're not interested in
helping people, so you'd have to take the initiative to put yourself in
from of them. I don't think they'll put you in a different timeline just to
correct your 2015 accident.
But in your case, i think the best thing you can do is to pray, and
secondly, you can quantum jump back to the past and rewrite what happened
in this timeline with your mind. Google quantum jump, you'll get it. It
will have some effect.
But do you really want to change things? Because there's good in everything
bad and bad in everything good. Sometimes, the problem to solve is not how
to change the past, but the problem to solve is how to fix the present and
future in order to use your time now in the best way. If you changed your
mistake, maybe you would rob yourself of the purpose in your life that God
has given you. Maybe this purpose is your challenge.
Good luck then.
