EDIT: Apologies, this was posted more or less at the same time as you post, so it's largely in response to your first post. Maybe more details of your previous experiences your alluding to could frame this better. But anyway, in response to earlier...
You should go to a doctor as moleculeoflife suggested, you may think they may be judgemental (and as I don't know your local doctors, I couldn't say) but for me they weren't at all surprised by what I saying even though I said I was worried about killing other people. It's fundamentally not a police issue, and a decent doctor will see that.
In terms of treatment, I'd suggest decent CBT over drugs like SSRI from my personal experience. SSRIs in young people produce suicidal thoughts and give extremely vivid dreams, both of which they did for me - making me feel worse than the OCD they were supposedly treating. Maybe the best option is to try them, but to mention to your doctor you'd want to pull out fast if they weren't working out for you - for me I was advised to stay on them for 3 months after starting which I found pretty terrible, as I already knew in month 1 they weren't working out.
In terms of going to the police, I rang the emergency psychological helpline in my area. They didn't really help, they're only after people dissociating from reality from reality who are a danger to people, so people in that situation (if they're decently aware of these kind of issues) would I'd imagine give you similar advice to me.
I guess the best thing to try is to wait it out and try exposure therapy (from my own experience I think long term exposure when you've learnt about some CBT principles, if the only real way to break out of OCD, with or without therapy). Decent exposure would be talking to your mum about it, however that comes with the huge caveat of whether she's the kind of person who would be comfortable with such a discussion. If she isn't, you can get a pretty crap response and so regress - I'd guess you'd have to make that judgment call.
You mention your lack of fantasising about killing your mum, and that's more or less fundamentally the point - someone with a fundamental desire to kill someone does have a fantasising element about it. It's a good differential between yourself and a would-be serial killer.
Anyway, I hope you get better, and consider your options before moving forward in terms of an appropriate therapy. You should read a little about CBT and make an informed choice, if you can covertly buy an OCD self-help book you might get a better appreciate to inform you choices. Good luck, and though it's impossible, try not to worry so much.
