Is it worth it or not?

Hatred; using someone else's mistake to punish yourself.

What difference does it make anyway? Some tells me not to hate, even my mind tells me so. Because hating is only gonna make myself even harder to bring things to an end. Some tells me to continue hating, because continue hating can make me forget thoroughly. Is that so? My heart doesn't know what to do actually. God, this is when I need u. Why aren't my prayers answered? Please be fair this time. My heart's really too fragile and tired for this.
