I have car anxiety

This morning at 3:45 I was awakened to the sound of a car alarm going off. "My car alarm?" (I said to myself, with my heart pounding out of my chest). But I wouldn't know because i have never actually heard my alarm go a full cycle. This alarm went a full cycle and then shut off. Now I am thinking "ok did they smash my window, pop the hood and cut my battery wires?" (As I was so helpfully informed about by the guy at Circuit city who was trying to get me a buy a back up battery for my new alarm system for the nice tidy sum of 89.99) "Do they actually DO that?" I said to him. "Oh yeah in about 3 seconds flat." Thanks super helpful circuit city man with rotting teeth and cigarette breath- you have just made me pee myself everytime I hear a car alarm go off. SO back to my story- I get up, grab my keys to go check it out from my porch- (more like a cement slab, but who's picky?) Of course I cannot see my car from there- it is just ONE space away from the car that I can see- I strain over the railing, but to no avail. I decide that i have to go outside to check it out. Now of course this doesn't happen when my roommates are home so if I get attacked in the parking lot, they will hear me scream. Oh no- they are away at an Institute retreat and I am BY MYSELF. So I quietly sneak out my front door and get a look at my car- but it is still pretty far away, so I can't see it very well, and I am not walking across the dark parking lot by myself at 4 am with possible "car hoodlums" about. So I just go back inside, get back into bed and lay there WIDE awake for another 20 minutes thinking of all of the possible scenarios. I am pretty sure when i fall asleep that my car is going to be gone in the morning. Luckily it was still there, with no harm done. I think I am going to buy that backup battery. It's times like these that I wish I was married and could send the hub outside to see if the car is ok.
