question (philosophy)?

[Philosophy 101]

ok so has there been a time when you felt that you were going crazy??

for example, ive had this thought in my mind for 3 years i think about it all the time....

its about a person that i met 3 years ago, met him just once...we have not seen eachother since..... i cant forget about him....ive done everything and anything to forget about him...its driving me crazy...its been 3 years, there is no way that we could ever meet again, ive lost all contacts i dont even know where he is .....i think im going crazy what do you guys think??

I like to think that im an intellegent person, i have completed 3 degrees, and im well on my way to pursue my 4th degree in medicine i feel as tho i have the ability to rationlize and think logically but in this case i feel like an idiot
i am also an attractive person ive dated several times...never had trouble finding partners.........so why am i so hung over this guy
THERE IS NO WAY IM IN LOVE WITH HIM....I DONT KNOW HIM LOL
hahah i know this question should be in singles or dating....but id rather have a philosophical approach to this, philosophy tends to seek a deeper meaning
