You can’t suffer in the past nor the future, you can only suffer in the present moment.
Accept a situation as it is, embrace it and say I love you no matter how much it hurts. I love you and I am grateful because you taught me how to accept myself and how to convert hate into a love.
You can’t hate a person that you really loved. The only thing you can do is to lie and hurt yourself. Accept it and continue growing the love you have inside you.
