How do i even respond to this question!
Well one person said nothing and i believe her for i know her determination and energy. Nothing should be able to come in between yu and your happiness but sometimes life happens and we cant avoid but slide in an obstacle. Many times we also think its the best way to live (be sad while you have others happy). Well, you cant pour from an empty jar, you will realise later that those people you sacrifice your happiness for are also not happy because i mean emptiness cant fill emptiness.
But like i said, sometimes life happens and self happiness is tucked away and we sulk. Happiness is like self love.
