How to keep going after heartbreak?

My x and I broke up a few weeks ago and I still can't get him out of my mind. Nothing helps. The reason why he left me says so he is because he is still hurting from his x before me because she used him for sex and took his money. I am totally opposite. I want him so badly. I have tried to move on but I wont budge. I love him so much but he doesn't know if he loves me in return. I feel like I'm dying. I am smiling less and starting to think about suicide. I have talked about it to my friends. They think that I should just move on. I have tried but I just can't. I dug myself deeper in then I should have gone. I am only 15 too. My heart hurts too. Yea it is actually my heart. I know this sounds pathetic and totally sounds like I am very dependent but I need him to live. He made me feel happiness and I used to be just lost and confused. Now I'm back in that stage and it's worse then ever. I know I need to get over but I can't. I never felt like this before after my other boyfriends either. I know it might be a waste of my time but god I have nothing but time. All I have to look forward to now is school and death. I have nothing. He took my heart and still flippen has it.

That is not true. You have plenty to look forward to at 15...you have your future, your whole life ahead of you, and many more guys to come. Your reason for existence should not be based on one guy. I wish I could start at 15 again. I've experienced some very tough heartbreak in my teens. Looking back at it 10 years later..you'll question why you even felt suicidal and depressed over a guy who doesn't have his head straight and walking into relationships with such baggage. It's easier said than done...I know. You will need to give it time. Time is the worst painkiller. Try to be positive and find things to do that will distract you. Go out with your friends more. Do you really want to exert your time and effort into a guy who is pondering over someone else and the pain she inflicted upon him? This feeling of wanting to kill yourself is probably derived from a feeling of emptiness, loneliness, co-dependency, and self-esteem issues...it can't all be him. This most likely stems from childhood experiences or issues within your family. You must look within yourself for fulfillment. A man should only be there to compliment who you are as a person...not be your other half or your reason for existing. Look at your life within a positive light...away from negativity. Focus on your strong points. He lost you. You didn't lose him. He obviously has trust issues. Many adults will tell you that you know nothing about love at 15, but I've been there so I know exactly how you are feeling. Good luck, and keep your head up.
