I think I have OCD?........?

So, I've always been a little bit "obsessive" but now I think I'm really developing OCD. I'm 17, and I've heard that girls are supposed to develop it when they hit 20 or 21...so I feel like it's just going to get worse from here. I don't want to tell anyone about it, because my mom already makes fun of me for being "OCD" enough as it is, and I don't want to prove her right. If people could tell me whether or not I have OCD, and if so, how to fix it, that'd be great :)

Ok, so here's what I do:

Wake up at 5:03 (5+3 = 8, 8 is a power of 2.)

Get out of bed at 5:29 (5+2+9 = 16, 16 is a power of 2.)

Get dressed, run 4 miles. Leave at 5:47.

Back around 6:45.

Shower for 8 mins, get dressed, leave for school at 7:36.

(At school, schedule's pretty normal. No control. Go home, some days stay after school for certain things.)

10:07 lay out clothes for bed, brush teeth, get ready for bed. Room has to be spotless before I go to sleep. Backpack in corner, eight pencils, alarm clock set to 5:03. Go to bed at 10:52.

I have other things that I have to do during the day...for example, I practice my flute for 62 minutes. Running every morning. I haven't missed a day since November when I flew to California. I drink 4 cans of diet coke a day.

In case you haven't noticed, everything has to be a power of 2. When I was little, I thought that powers of 2 were the only "good" numbers and that by doing things in that number I was "keeping monsters away." Now I'm older, I know it's ridiculous, but I can't stop counting to powers of 2. I flick lightswitches or close doors 2 or 4 or 8 times. I always count to 8 in my head. If I mess up a word or phrase, I'll make it so I've said it 4 times; for example, I'll be talking, and I'll say, "Well, I think that we'll have got to...I mean, got to, got to, got to go tomorrow." I don't know why. I can't stop. There's so many other things, too. But this has gotten really long. I don't want to tell anyone, because I'm afraid people will think I'm weird. How do I cure myself without telling anyone, especially my parents?

Thanks.......
