Don't promise if you can't keep it... Don't create expectation if you can't meet it .. Don't impress anyone if you can't sustain it... Do only the things which you can do it in your life...
Losing yourself when loving someone does mean your love is sincere but remember it also means the other person is not the same way you feel because you should win in life with love but here you're losing... Then how it's love?
How can someone change this much? How can someone just change? How can someone hurt this much? How someone can lose self respect? How someone can love this much? Oh then how it is called love??? Shocked and Surprised...
