What is the greatest feeling after all ?

They say that you came alone and you are going to go alone, and yet we spend our whole life trying to be a part of so many other lives. Why?

I would say that the pain starts from the time we are born and with time we just learn  to subside it. The moment we come into this world, we are the reason to give pain to our mothers. Yes, out of love or motherhood they do say that it's beautiful and that pain meant nothing because it gave them us but look at it practically, it is just the beginning of our lives and we already put someone else through PAIN.

The pain one feels when you have your first heartbreak. They say it makes you strong, it makes you wise and it gives you strength. Okay, if you are done trying to console the broken heart let me put across my point of view, it's nothing but a reminder. The reminder that the most powerful feeling is actually pain. They say you will forget everything when in love and that Love is the most powerful feeling, Maybe. But then why is it so painful to see your love breaking your trust? When you hear those cruel words from the one you love, all you feel is PAIN, the feeling of someone crushing your heart, the pain inside you becomes more real. 

The pain of losing someone. With time we all get attached. We as humans depend on people for anything and everything. Our close ones mean everything to us. Our world revolves around them. We all love and we all build families and friends. Not just this but we also have certain enemies or the list of people we are not very fond of. The point is that all of them become a part of our lives. Do we all somewhere forget that one day, it has to end? Not the relationship, but the human. Today the ones we are very close to, would not be there anymore one day! The growing love and support we build is just going to die. If not mentally then DIE PHYSICALLY. All it will give us at the end would be PAIN. 

Is the feeling of pain the greatest feeling actually? Are we all just living in denial?
