I am a medicine student at some university,  Before 3 years there was a girl I met ,back when I was a freshman student.At first I started talking to her for a fun but we ended up being best friends ,but in the process I guess I started falling for her, then  I confessed my love for her,she refused, but just because she said she wanted me as a friend I didn't stop hanging out with her, I started trying to treat her like  a normal friend though I was dying inside, even after 3 years my feelings for her couldn't change I suffered with her love plus med school and that's hard. and now I lost the confidence in my looks,body and everything.now I'm  thinking of ending it wit her,but am afraid of stopping to talk to her  that I won't move on,And I don't want her to lose a friend like me ....
