I've been sabotaged!

I think this might be the end for me. Early yesterday evening I started to feel incredibly ill, with it carrying on to today. I haven't felt this bad in a long time so I have my suspicions on how it started.
While walking around the area yesterday I could have sworn I saw a caped figure following me around every now and then.

Now, this could mean one of two things;

• I have a rival, in which case I need to get back to being healthy as soon as possible.
  
  Or...
  
  
• I actually am ill and I was hallucinating.

Now if you'll excuse me, I need to go pass out.
