So it was to be that you'd never stay together for that mystical forever everyone talks about. Loving and losing twice in less than a month is hard for somebody your age, still a teenager (whether you think so or not...if you've got 'teen' in the age, than you're still a teen) searching for an identity, still pretty fragile where issues like love are concerned. I can't honestly say I've been there myself, or know what you're going through, but perhaps instead of dwelling in the darkness as we often do, you may want to try looking back upon the good times, know that you were able to woo 2 lovely women to your side, and use that to pick up the pieces and move on. The first love we find rarely blossoms into perfection, and so it is with many people that the first and the second love should break down. Hopefully I've at least said something worthwhile and am just not wasting my time musing upon something I've no experience with.
Hope you feel better soon
