So, I believe I'm in love with a fictional character. What to do?

So I first "fell in love" with this character when my grade three teacher started reading the Harry Potter books in grade three. That was when I was eight. Now I'm 19 turning 20 and I'm starting to realize that my fears that I could possibly be insane or there is something very wrong with me or that I'll never love anyone as much as I do the character Draco Malfoy could be a reality. I don't know what's wrong with me. Whenever I read anything about him I get this feeling like someones rubbing their fingertips on the insides of my ribcage as disturbing as that sounds, it's a hard feeling to describe. Like really SEVERE tingly good feeling butterflies that's ALMOST painful but definitely not and heart pounding. I'm definitely not short of guys liking me in real life, in fact I believe there's quite too many and I have zero interest in any of them which my best friend and any girls around me can't understand why as anyone would be lucky to be with a number of them. I have really tried to like a guy who actually exists or even another fictional character but I get no feelings from any of them even comparable to the feelings I get just reading about Draco. It feels like I'm pretending no matter how natural I try to create relationships with guys in real life. He's not even my "ideal", as in if I could choose personality traits or appearance of my perfect guy it would not be his. I "love" everything about him and I wouldn't change a thing about him described in the Harry Potter books. I put love in quotations because this must be infatuation. Right? But then don't I belong in a mental institution if I've been infatuated with a character for twelve years with no signs of stopping? He is almost all I think about, I dream about him constantly, and half of me doesn't want to stop because of the feelings I get and the utter devotion I feel. Should I get some mental help? Does the fact that I recognize that I very possibly need mental help suggest then I don't need mental help? Let the insults flood in! Haha.
