Depends, georgie...
If you were really attached to her, then of course, you're gonna feel loss.
I went through the same thing a few months ago, and the best remedy I can find for you is to get out, and meet a ton of women. Don't look for another LTR, either. Right now, you just need to get out to feel good about you. Jumping into another relationship isn't the answer. That will just hurt you more in the long run.
Go out, and have fun!
