I think you're not yourself at the moment and you need a good, positive support system whilst you are going through this phase.

Many things can trigger us into self harming behavior when we feel in turmoil and don't have a hold on our emotions.

I purged in university but haven't quite got past the self harm just yet. It manifests it's ugly head when I'm under a great deal of emotional distress. Like when I lost my job a month ago I couldn't help but punish myself.

You are not alone but you do need professional guidance.

Be safe.
