Welcome, Nuleaf. I'm new here too. SR is amazing and I have found a lot of support and great advice here so far. I'm on day 3.
I'm not sure where you're located, but I know in the US a lot of places will go a little easier on you (as in, not fire you) if you admit you have an addiction and are seeking help. As MsCooterBrown said, you might want to check with HR.
Hope you find something that works for you - post often, read often & take it one minute at a time.
