What wrong with my Virgo friend?

I really need a help, i have a virgo best friend she's a girl,its been a month now since i confessed my strongs feelings to her,(by the way she knew that i have liked her before my confession) and she became weird about it and said : "it is okay, i will treat you normal ,you still my friend" but things went awkward cause i have issues at home ,and now everyday my feelings become stronger :/ and when i like someone i dont treat him as usual because i become very shy , and dont know how to start a conversation.We really trust eachother,we ve been honest and loyal ,we had the strongest friendship ever.The thing is today she told me that i changed ..and i dont treat her like i used to,and she was mad..awkward and distant ,we rarely talked to eachother these 3 days :/ , she was so cold, and apologized and she said : dont be sorry u did nothing to me .I have a lot of issues , and i really like her more than a friend (i just want to be her friend its just that i didnt wanna hide my feelings for her cause our relation is based on honesty , not pretending ),and said im not mad at you, but she was speaking cold..and i told her why i changed,(depression change people),i just dont wanna lose her , our friendship is the most precious thing,so what should i do? i ve already talked to her..but things are going awkward , distance didnt work for me by the way we still friends i just dont want her to think that im not that person anymore i really need a help :/ she even deleted her facebook account so i cant reach her ..she deleted it cause she spent too much time in facebook ,and she wanted to spent more time studying
and today i spoke to her, she said : "Now i dont wanna talk to anybody .."she's very mad ! and i asked her the reason why she is been cold , she said:"nothing at all" -__- so should i not bring the subject again, and give her time and space?? or what :/ (im a gemini but it doesnt matter ,im her best friend in the end)
