Paranoid about Cooking

Options
Yello ladies and gents,

I have grown an affinity for cooking, but the problem is, I have this sort of 'paranoia' of the stove. Like, everytime I have done my cooking, there still is something wrong. Like the kitchen is about to catch fire, or something, once I leave the house. Anybody had something similar in their experiences? How do I know if there is really something wrong, and how long do I have to sit next to my 'safe stove' until I am assured it's really safe?

Just some background about this: I'm 19, and quite unexperienced at cooking. I have learned the basics of it all, but when I was younger, my mother never really trusted me in the kitchen, and I suppose that still has followed me through into my late teen years. I always check the gas 3 times before leaving, but I still prefer if I didn't have to be so scared about cooking all the time.
