Scared of bed bugs, should I go and sleep in my parents bed?

It is now 4am, I am really convinced I have bed bugs in my bed (woke up with rash-like bites and saw one in my pj's tonight) although my dad checked my mattress and thinks I'm lying and just seeing things. I am in my brothers room but still cannot sleep because of my paranoia and fear..I am sooo tired and the only way I can get some sleep is if I go to my parents bed, despite me being 14. Should I or should I not? My parents will probably be real p*ssed off. (btw sleeping on couches don't work for me)
