Hi Vickina, accept your pain. Have good long cries. It's okay to be hurt and sad, and it's okay to be alone. It's okay to feel like you have messed up - accepting responsibility for your mistakes or shortcomings is healthy. On the other hand, you must also accept that you are a good person, and that you did your best and you're not the only one who made mistakes. Of course, a stage of denial is completely natural, but acceptance is the key to being able to start moving on.

as i see, the best effective way is to find a new boyfriend.

Hello Vickina, You don't have to forget him , just concentrate on remembering the wrong things he did to you and you will feel better off without him. Start a brand new life , make new friends, engage in various activities. You are very young and you have your life to live ,so let bygones be bygones ;) Cheer up !
