I think I'm being stalked, advice needed asap

OK, so I'm a little flustered. Let me just explain my situation because I'm in a bad position in my life at the moment and I'm worrying it may be just paranoia.

I gave up a promising football career to get with the love of my life and it's not going so well, really only staying together for our kid (I'll answer questions on that too if anyone has any). I currently work as a security guard for some shitty firm who have me doing jobs on stadiums and high profile university events, college football stuff like that. It's a dead end job and I have no prospects of climbing the professional ladder, so to speak. To make matters worse I was recently in a a really bad train crash that actually made the news, I obviously survived but the whole but the whole event was disturbing. The strange thing is, ever since the train crash Samuel L Jackson has been following me around telling me I'm a super hero. Has this ever happened to anyone else? How do you get rid of him?
