The Front Door

I don't like being all alone in the house. It's suddenly like every creak's an assassin flying down the stairs, knife raised, or every time the pump goes off just because, there's a pirate who's trying to scare me.
I always lock the door when I leave, and I've learnt to always put music on, because it's distracting enough to stop me from analysing every sound in the house, but not so distracting that I can't focus on anything.

And then. There. Is the Door.
The front door: so I went down a couple of days ago to let my mum in, and this is around the same time that I was telling her that lately my imagination's been working overtime, so sometimes I can actually see in my mind how a teleporter murderer might turn the corner and kill me with a throwing star. So I let my mum in, and she stands looking at the door for a couple of minutes, and then tells me that it looks like someone's been trying to break in, and that they're close- almost breakable.
I'm home alone a lot, just because of all the frees that I have and I hate waiting around in school, so I come here, and now it's like... Am I supposed to lock the door when I'm home alone? Because it's starting to seem like a really logical idea.
I mean, loads of people must do it.
But then I don't want to tempt the fates, you know? And getting super anxious about all of this isn't going to help with me handling stress.

Hence the post title. The front door has ruined my composure, and my calm. Every time the phone rings, I'm terrified that it's going to be someone waiting outside who makes me leave the house and go to some drop off point where some dark vehicle picks me up, I'm bound and gagged and driven to a secret location where I'm held for ransom, but what choice do I have? Even if I stay inside, the front door is zero help.
I need some doughnuts and some tea so badly right now, seriously.
