Life is best when all aspects are balanced. If you are obsessed with any one ignoring others, life is hell. Thus, if love is everything for you, this is hell. Life was hell for Majnoo and Farihad.
May be that you are disappointed in love or fell out of love which makes you think so otherwise I believe this world is rotating on the wheels of love...
It is according to the love we had. If love becomes over and possessive and irritating then it become hell. If it is not possessive and not over then it will be like pleasant and heaven.
Love is anything but that....it is only what people choose to make of love - whether heaven or hell, but then if its something that harms another individual, then it cannot be called love in the first place.
