mid-life crisis?

of late, there is a great feeling of going something all the while... it is driving me nuts...whenever there is a little free time, i am getting bored. is this normal? like right now, i had no intention of wrting... but am...why? why can't i just let myself be... why do i keep flogging myself... aha, this is a phrase of an ex-friend, ex because we have just lost contact... at one point, we used to agree on everything and she was exactly in my present age, when she said this... mid-life crisis? though i seem to be happy otherwise... mid-life or no mid-life...
