It is so bloody hard to deal with such condition . .
There can be so many reasons of breakup!
Broken trust ? Cheated ? Faded love ? Bore ? Too many fights ? Change in behaviour ? Fear of future ? Parents ? Etc etc .
I know this situation sucks .
But always remember
if your love is strong enough nobody can break it , and it will come back to you but if it is not , It was never true , and was never meant to be!
Always stay loyal from your side , never break there trust , never do anything which can hurt him/her.
So that , you wont regret on yourself that you didnt give your 100% , or probably it could be your mistake . .
Atleast you wont blame yourself , you did everything but the other one is a povert who didnt understand your feelings .
And if you did something wrong and yoy feel guilty about it , then you deserve a chance!
If they love you they will come back to you. . And show him/her how much you love them , how your life has become after him/her.
And then try to forget , it is the only option left
Never think of sucide NEVER EVER
Alwys think about your parents who love you so much that they can do anything for you.
Set your routine .
And give you time to your friends , join somthing new .
Go to party , do somthing productive , try to built new relationships . no there is no harm in making new relationships , because if they dont care show them that you too dont give a damn.
Think negitive things about them , how they break you , how easy it was for them to go away , listen to cool songs . I know this may sounds funny but trust me it helps alot!
And sometimes it is important to go away from there life to let then realize your importance! To block them from everywhere.
This may works!
All the best
