Can you lock an iPhone/iPad wallpaper?

I don't know why but whenever I'm not around my sister will take my iPad and change the wallpaper to something annoying. I'm really starting to get tired of it and I'm wondering if there's anything I can do to prevent the wallpaper from changing (besides setting a pass code on my iPad)

Is there an App or Program that allows you to set specific timers?

I'm looking for an App on the iphone that allows me to create a timer of sorts. Basically I want to use it for an exercise routine I'm looking to do. Basically I want to set it for 30 minutes, but have intervals in it so that it alerts me when to change my exercise. For instance, say I want to try the 7-minute workout. The 7 minute workout has 12 exercises where each exercise is to be done every 30 seconds with 10 second rests in between. The program or app would basically alert you every 30 seconds then every 10 seconds until 7 minutes are up. Is there a program that allows you to do that?

I always feel like I'm being watched?

I share a labtop with my mom. I have a password and everything, but I always feel as though she can see what I'm doing and can somehow see what I'm doing. Which, isn't exactly a problem. I'm not doing anything bad. Also, I have a jailbroken iPhone. A few weeks ago I got a virus, I fixed it, but ever since then I've been terrified that someone can now see exactly what I'm doing on it, or can spy on me from the camera.

I mean, I know it's unlikely and I sound crazy, and part of me knows it's weird, but part of me thinks its true. No matter how hard I try I can't stop thinking someone is watching me, one way or another. Like, through my window. Or maybe it's a camera in the walls, or maybe there's a ghost watching me. I actually do think these things sometimes, and like I said, I believe it but I also don't.

Am I just crazy or is there something wrong with me? I've had anorexia, I've self harmed, and I was abused as a kid. At the moment I think I hear a ghost breathing. Not even kidding.
