Freaking myself out

I don't know why but for the past month or so I have been kind of obsessing about preparing for a disaster.

I am not a proponent of the whole 2012 end of the world scenario etc. but for some reason I keep thinking about having a back log of supplies/ food/ first aid stuff/ water etc.

I can't explain why I feel this way, but I do.

You have to understand, I am not the type of person who goes off the deep end about stuff, or over reacts, but for some reason I cannot shake this feeling that something bad is going to happen.

And it is kind of freaking me out.

Hubby doesn't understand, but through the years I have learned to trust my instincts. Example:
About 11 years ago right after we built/moved into our home we decided to hire someone to finish off our basement. We interviewed a few guys and hubby decided he liked this one young guy the best- plus he was one of the lower bids. Hubby said "he's just a young guy starting out trying to get business".

There was something about the guy... I couldn't put my finger on it, but I REALLY didn't want to use him. Ultimately I conceded and hubby hired him.

We had nothing but problems with the guy. He began work on finishing our basement at the end of July. I wasn't working at the time so I was home all the time- and half of the time no one showed up to work. We got excuses like"my foreman was in an accident", "my men didn't show up", "we are just finishing up another job and will be there as soon as we're done". There were other issues with him but too many to list.

This went on until the week before Thanksgiving.  
YES I said mid November!
They built our entire home in less time than it was taking this guy to finish off our basement!

Finally it was Thursday the week before Thanksgiving- when I finally gave him an ultimatum.
(we were supposed to leave the day before Thanksgiving (Wed.) to go to my in-laws for the holiday) 

Either have the work done by Tues. evening or we would call someone else to finish the job and he would only get his initial payment (half of the job + the money for the supplies he used). He asked if he could work through the weekend to which I said sure.

Hubby struggled with this- he is no handy man. But I was DONE! I was the one dealing with guy (when he showed up). The job was almost complete so he should have been able to complete it in the 5 days allocated.

He didn't. (Probably a blessing in disguise looking back)

When his worker showed up Wed. morning I told him that all of their equipment was on a tarp out back & covered with another tarp. I told him to tell his boss he did not meet the deadline and that we would find someone else to finish. Within the hour I received a phone call from him. I was civil, but told him thank you for the work completed but we would be finding someone else to finish- within the hour he had people there to pick up his tools.

The people we hired to come in and finish (mainly the plumbing) found that he had installed the toilet lines incorrectly and  had we not fired him and had them come in we would have had raw sewage backing up within the walls of our home from the kids bathroom on the second floor.

So ultimately it was a blessing that I finally trusted my gut and fired the jerk!

I later saw his pic on a watchdog list as a pedophile. 
(Yes I am SURE it was him)

So... this feeling I am having...

kind of freaks me out.
And I am slowly stockpiling canned foods, first aid supplies, water, etc.

Call me crazy, but *shrug*
I hope I AM paranoid!
