A break up does not mean your life is useless it just means that you are just starting and you need to wake up .You need to forget the past and move on , it took me four month for me to understand all these are bound to happen it makes us to understand life .
If you were end up with that person do you think you will ever be happy ? as for me I will say no it will make me regret it that I shouldn't have taken these path .
You need to stop thinking and start living ,be happy have fun , hang out with ,date and don't stay with only just one person , at the end you will not feel pathetic that you were being left out .
Look beautiful , sex , happy do those stuff that you love so much that makes you a better person , be the person you really want to be and don't let someone tell you that you are worthless you have a beautiful thing inside of you that can make a great impact and difference in thousands lives .
don't go and commit suicide or if you had a baby with the person think of embracing and not adopting if you meet the man of your dreams then be over happy no matter the stomps you pass through .
Be strong and courageous
