Did I just ruin myself and value?

My boyfriend of 3 years deeply wronged me and I really thought this was something we could work out. However, this hurt was festering inside me and it wouldn't stop until I proceeded with my plan of hurting him back.

I thought it would make me feel better after it was done but it didn't. Even though I managed to hurt him too (just like he did to me), I ended destroying myself. It solved nothing. I feel worse now. Did I just ruin myself and my value?

I feel as if I've scooped to his level, so low, as if I've just degraded myself forever.
