Did i creep out my female friend?

So long short one of my best friends and I are co-workers at a fast food place so we pretty much work together on a regular basis. We are both in college and she is pretty good looking, you know the type of girl who spends her weekends buying clothes, texting her friends and posting stuff to Instagram. so anyways, I'm really attracted to her, and i think i've been pretty good at hiding it, but I think i made one massive mistake recently.

Last week when we had a shift around the same time when we needed to change, one person was already in the crew bathroom so she apparently had to change in the crew meeting room. I didn't realize what she was doing until she started looking at me funny for staring at her while she slowly pulled down her pants. I turned away for a second because she looked at me with puppy eyes since i guess she didn't want me to see her naked or at least in her underwear. I realized that she was changing at that point, but i had a massive hard on at that point and i couldn't resist staring, so as she was looking away from me, I turned around again and tried to see what i would get to see. She hat the cutest light green underwear and a really thin bra so i could practically see everything, i could even see her ass crack, she looked so cute. I forgot that she still had eyes though. Unfortunately she looked up very quickly realized i was staring at her then turned around then moved into a corner. At that point she had practically covered any intimate skin. I feel so terrible i just couldn't control the direction of my eyes and i think i came off as a creep. after that she threw on her pants and started her shift without even looking at me.

Ever since this event ,which was about 2 weeks ago. She acts so weird around me. She used to always touch me whenever she talk to me, moving around me like i was a manikin, now she always seems to act so shy around me. Do you think there is still a chance for us to save our friendship or even start a relationship? what did i do wrong? it was just a small mistake in my mind.
