On purpose or for purpose?

What’s the point of holding on. I mean, honestly; who are we trying to impress?
There are people who say that “the best is yet to come”,
but they are just fooling themselves.
Pretty little lies to help them get through the bad times
But it’s been 7 years since I realised what I have
And since then there’s never been more than 4 weeks without feeling the infernal pain.
Even when medicated.
It’s exhausting,
And we hold on to make a point.
But what’s the point?
We surround ourselves with things that mark our “successes”
But the only real success is that we made it through the day
Without jumping out of a window
It’s been two weeks now
And the only thing on my mind
Is letting go
But yet, I hold on.
Is it the urge to survive that all living creatures have?
Or is it a sense of pride that I don’t feel
But is there, holding me back.
In 100 years, no one will remember
That you didn’t let go.
They don’t know now.
So what is the actual point?
