Fear/ Worry stone

The illustration of rolling away our own stone was like a slap in the face this morning!
I know I'm now 20 and supposed to be mature and grown up but that still doesn't stop my fears. A lot of you prob know I'm arachnophobic but since starting my second year I've found a new bigger fear. - being alone in my house surronded by silence. Granted I don't live in a very nice area (although only 1 stabbing to my knowledge since Christmas) so a little bit of scaredness is allowed to keep me in check with reality but still I need to grow up.
I need to roll away te stone of worry and fear of my ickle house being broken into whilst im there on my own. but how?
it's all well & good saying yea I trust God to keep me safe but I'm only human and when there's a noise outside the house my mind always thinks the worst why can't God stop my thoughts? did Jesus feel dread? did his mind play tricks on him to scare him? or is that a human trait he never got the pleasure to experience?? hummmm....
don't know why im waffling about this really guess it's coz im going back to uni 2moz & Paul has had to give up his holiday to spend in my house whilst im at work just so I'm not home alone grrrr I need to be as strong & brave as an ox!
Here's to a new week...
