Am I obsessive?

Things that may or may not make me obsessive:

1. I have to line up the mail, according to size. Largest envelopes in the back to the smallest envelopes on top.
2. I have to sort my money by amount, largest bill (like a 20), then 10s, then 5s, etc….and they all have to be facing the same direction.
3. I sort my Skittles, M&M’s or fruit snacks by color and eat them smallest group to largest.
4. Since I’ve moved into my apartment, I’ve noticed everything has to be in place (or at least where I placed it) or it drives me crazy until I fix it. Even something simple like the way I arranged the magnets on the fridge.
5. My closet is organized by color and clothing. So, skirts first, arranged by color, then pants, arranged by color, etc.
6. My shoes are arranged by color as well.
7. I wash my dishes from left to right. It’s stupid, because then I put them on a dish towel by the left side of the sink but it’s the way I do it. (My mom says it’s backwards and I’m weird. LOL)
8. I'm constantly afraid (if I'm at the movies or someplace) that someone is going to steal my purse or the credit card in my back pocket. So, I am constantly checking to make sure my purse is still there or my credit card (and car keys) are still where I put them.

I think that’s it. I’m sure there is more I do. I just know, that if I don’t do these things, I get really anxious or jittery. Am I OCD or just weird?
