If you can ride out the emotional storm,it will get better. I promise. Maybe your girlfriend leaving you was so that you might be free to meet the one who IS right for you? Or this may not be a permanent breakup-who can say what the future holds? Take an old Mom's advice. I've got a young son,& I know how hard a breakup can be on young men.I even remember being young myself. I remember feeling like i couldnt breathe because of misery. We ALL feel that way, & the younger you are the worse it is! I know you think the pain wont ever go away,but it WILL get better,I promise you! Either you will get back together, or find someone better. Talk to someone you trust about this.
