Clueless

One of my friends is a photographer, he was in a panic that poloroid is shutting down one of their last factories...basically I'm asking is there anywhere to get film anymore or are photographers all expected to go digital now?

Last year I became very close to one of my teachers, got along with her really well, had a lot in common, etc. After a while she was constantly on my mind and I began to wonder if maybe I was in love with her and if I was a lesbian. I am almost positive she is a lesbian herself, she is no longer my teacher, and I'm of legal age so part of me keeps thinking maybe it would work. I keep imagining she also has feelings for me but is also afraid to say anything. But part of me also knows it's probably pretty unrealistic to think I could ever have a real relationship with her because there's just too many factors involved.

I tried writing a letter expressing my feelings for her, then ripping it up but she's still on my mind. I don't want to tell her because I'm afraid things would be awkward between us afterwards.

What should I do? Should I try to get over her? How?
