My girlfriend says she wants a break after 3 years?

I've been with the love of my life for 3 years...no problems...no fights...just love all the time. then out of the blue she tell me she doesn't think our relationship is healthy for her anymore and she needs space...i live 100 miles away from her and I only see her on weekends so there's already plenty of space between us... but she said I've become to dependent on her love and she's worried about that...she said she still loves me but she's not sure she wants to be with me anymore...i was completely destroyed and didn't eat or sleep for 3-4 days...she said she wants me to forget about her for now (no calls, texts, nothing), live my life and do things for me...the problem is all I can think about is how bad I want her back and how much this is killing me...seriously EVERYTHING reminds me of her...i know she's not doing this to date other people...but I've talked to her everyday for 3 years and don't know any better :(...its been a little over a week since this all happened...i talked to her friends the other day and they said she's acting like her normal happy self and there's nothing bothering her at all...as for me its a struggle just to get up in the morning...I'm so confused as of how we went from 3 years of perfect love (I was her first everything) to this... I'm willing to wait and give her the space she needs until she figures stuff out...but I feel like everyday I don't talk to her is another day closer to her calling me and saying she's happier without me and I'm scared to death I'm gonna lose the love of my life...any advice helps :,( thanks
