What to do with negative energies?

I'm putting it here because I think it pertains to the loa somehow.

What I mean with negative energies is for instance someone does something that makes you mad. You're gonna have to deal with that energy in your body now.

I recently discovered you can send the energy back to them. So instead of going around with a bad feeling because of something they have done, they can have it instead. I have no idea if they actually get it but it feels better intending it so

I'm pretty sure you can use these energy to manifest as well but it's not very comfortable.

Of course you can use it to just go and beat them that would work too.

Any other suggestions?
