hey, Myoasis89
I exactly have had an similar experience before.I mean i had a crush on my teacher and get over-attached to her mentally until it turned out to be too much for me.Yep,i wasnt good either at that time. Depressed though i was doing good grades.No such things as close friends for me.
And finally it turned out that she didnt care the way i did or i hoped.I got hurt and everything. I thought it was the lowest period of my life and once seemed i could never got it over.

Well, big girl ...keep your head up and send my best wishes for you.
