I have been going through serious heartbreak, I'm not able to deal with it. What to do?
Thank you for submitting this question.
I am sorry to hear about your break up. It's always very difficult to navigate after a relationship ends. There is no right or wrong way to deal with a break up.

It is true that relationships may change your personality and the person you are so it is very important to find your true self after a break up. You can read more about that through here.
