Stop taking LSD and you won't have that problem.
Seriously tho, get a can of bug spray, a shoe, your mom or dad, anything to kill it. I hate those things. I don't care what people say, they kill bugs, and household pests, blah, blah, blah, they are still creepy as shit and of course poisonous (some not all; but that's still enough to make me kill any I see).
You'd be creeped out by them too if you had to grow up in Oklahoma, and every night when you had the urge to piss, you went to your bathroom (this was between ages of 8-12 mind you) and after turning on the light you find yourself staring at 8-12 daddy longleg spiders surrounding your toilet, and having to piss around them because you were too afraid to kill them because you thought the others would seek revenge.
