Nobody hated you, abandoned you, betrayed you, offended you or hurt you. Everyone has simply hated, abandoned, betrayed, offended, or hurt a part within themselves they projected on you.
So relax, and don’t take it personally.
A separate reality is a world of mirrors. Everyone projects on others what they cannot acknowledge in themselves.
Everyone is an autistic and separate being who sees others only based on themselves.
Hence, if you understand the madness of this world and want to move on, the first step is to realise that nobody really hates you or hurts you, just as you do not hate or hurt anyone. Everyone who hates you or hurt you, or whom you hate and hurt is inside yourself.
Yet this also applies to those who love you, or whom you love.
This may appear as a very reductive way of considering human relationship… and it is indeed.
It is an intentional reduction of the complexity of human relationships aimed at leading it back to its matrix.
Then the second step will follow.
