Recently my obsession with the girl I had a crush on since [year] really started bothering me. So I wrote her an email (although, she never reads her mails):
I don’t know whether you will read this but I got to write it anyway.
I have had a crush on you since [year], and the obsession is really
starting to bother me now. I don’t want to be obsessed about you
anymore, but trying to get out of it seems impossible.
I would really appreciate if you could help me here by telling me that
you are not interested in me or something like that… I feel that
would help me to elbow out these infatuations that I have.
Thanking you in advance,
