Don't spread hate. No matter how terrible they hurt you, learn to love. Just because you were hurted, hurting that person back is not a solution. Shaming that person online, talk bad on specific people you don't like, spread untrue stories; if you ever did that, believe me, you will stand line by line with the worst human ever existed. So, learn to love. If you cannot forgive that person, then learn to love. And love, is not only by showing compassion through hugs, or giving forgiveness, sometimes love is simply give a space for yourself to forget all bad things people had did on you and live a better life with no revenge or hate. That is also, love.
