As others have pointed out, you could put this interest to good use. What I would like to know is why you want to get over the obsession - is it stopping you doing things you want to be doing?
A few family members and colleagues are autistic and have “obsessive” special interests. Some of them are very useful in helping them forge their path in life and some cause trouble. I have a colleague who has needed some very strict workplace boundaries to be able to function without his other interests stopping him being productive. Not suggesting you are autistic, just underscoring I’d like to know what friction this interest causes you.
