Is it possible to become addicted to self harming?

So i suffer so much psychiatric crap ive given up remembering it all but my life is very up and down mood wise and even in the ups i cut myself. My therapist thinks im always in a bad mood and i been thinking about it a lot like just the whole process its like at the start, just pressing that blade against my skin i get a rush of adrenaline without even making the cut itself. Then just feeling the blade slice through skin is amazing, to watch the blood gush out of the open wound and stain everything around is so satisfying and then the rush of endorphins that just is so relaxing and i can lie back and just sleep and it feels amazing. when i first started it felt horrible and i hated it but ive grown to love it and am dependent on it now. i am not stupid i know that it is a problem and i need help but my counselor doesn't really understand the whole concept of dependency on self harming so if this is like really really crazy and im the only one this has ever happened to that would be nice to know and i suppose could be another symptom perhaps? I dunno that's kinda what im asking any thoughts much appreciated.
