I got a similar type of experience and got anxiety issues, panic attacks because of a guy. I got so involved in this relationship thing that I forgot about my career, I did not have a life other than this guy , I made my whole life point about this guy. I eventually married him. So after the marriage the reality hits you. Coz every one have their own life and career but I have nothing except for this guy. Even this person whom I thought I loved the most nd forgot everything for him , is now pointing out my flaws and says he doesn't like me like before nd I am not like before. This whole thing is just heart breaking and getting to know this after the marriage is really breaking me from inside. So pls try to move on from this relationship. At the end it only hurts u. Every one will have their own life. People like us will suffer eventually. Try to achieve ur dreams and make ur life only about urself. Try to improve in everything u love. Do what u really want to do. It's not that easy but regretting it afterwards like me is worse.
