A kindness of the perfection to serve purpose

I started to do something, that I threw myself into, being in university. I am now experiencing this sort of relapse, post-graduated, sort of feeling that I have lost something? What I thought I set myself out to find, what I searched all over for now seems trivial to me. I ask what is any of it worth. I am in a kind of denial, or a relapse per se from when and where I began this journey all for not.
