I know and understand how you feel. I'm in the same boat, but I'm trying to move on, and it takes a lot of willpower. It feels unfair that we are still hurting when the other party has moved on and is having such an enjoyable life. If you are having trouble moving on, perhaps you did not have closure. And if you did, and you still can't move on, well, try a little harder. Give yourself little treats for every little thing you do. If you manage to get out of bed, and that is a good accomplishment, reward yourself with something you like: a favourite food or something. If you wanna stop feeling so down, try cleaning up your room? Once you complete, like, say, your wardrobe, give yourself another pat on the back. Take small, little steps to get back up again.

Once you get up, you'll realize how much of a road you've still got ahead of you, so don't give up. You will regret wasting yourself on your bed, when half of the town could be chasing a hottie, which is you. Give yourself a makeover, pamper yourself, and stop beating yourself up over someone who's forgotten about you three years ago! He isn't worth it! Your lost time can't be found again! Doesn't matter how much you love him, you gotta love yourself too!! You can't let him have all the love, what about you?
