Just Started

I'm 20, and I just started burning myself. i'm autistic and have pretty bad emotional regulation. I've never self-harm before (maybe ripping my hair out or hitting myself when I was very stressed). This is the first time I've actively and purposefully injured myself because I felt I deserved it. I enjoyed it, but do I stop before it gets worse or becomes a problem? How do I stop? I don't think I can, though, guys... life is hard.
