Relationship advice?

For context, I'm a guy wanting advice from a females perspective. I'm feeling extremely anxious and feel depressed sometimes about a situation. what does my crush likely think of me blatantly being awkward around her and her friends and avoiding them for a whole year even after they tried to initiate interaction with me and to be friendly? This is a girl i confessed my feelings to, and she declined going on a date with me. she said she isn't looking for someone right now, and maybe another time. i could tell i made her uncomfortable, so i started actively avoiding her and pretending i don't notice her when i walk near her. I have blatantly being awkward around her, and she notices I'm avoiding her. They have now stopped trying to initiate interaction, so now I've left the church because of my fear about this situation. It's been a whole year since i left. is there hope that i will be able to have a friendship with her if i return or her friends? how will i ever be able to feel comfortable around her again if i feel this humiliated?
