She made you fly all the way to England so that she could tell you that she doesn't love you? Sorry, but that seems extremely fucked up to me. Normally, I'd say it is better to tell someone that the relationship is over face to face, but not if the other person flies from another country and plans to stay in yours for several weeks.
As for "I will always love her forever"...everyone says this after a breakup. Maybe you really do love her, I don't know. But you've only spent two weeks together? Can you really be sure that she is your soulmate after 2 weeks?
I know you're feeling really badly now, but just remember, time heals all wounds. You'll feel better eventually. If you're just moping around the house, stop it. Go find an activity to do. Take up a hobby. Do ANYTHING which will get your mind off her.
Sorry if any of this comes off as being harsh. I've kind of been in your position before, although nowhere near as drastic. I remember letting someone make me miserable for awhile. Now, I kick myself in the ass everytime I remember how pathetic I was (I am in no way implying that you are, but I really was). I got over it, and can honestly say that I'm a better person after experiencing it. Anyway, I hope you feel better and get over her soon. And like someone above me said, you'll always have us
