What have I become?

My darling and me in a much happier period in my life. I have reached to somewhat of a crossroad in my life. I find myself 'bummed out', stressed and pretty much lifeless these days. And for what? A $4k salary at the end of this 2 years? A nice car? A nice house? All this pressure to pass exams cum interviews, to be a good leader, to be a good boyfriend, to be a good son, to be a good everything basically; is beginning to take its toll on me.
I get irritated easily these days and I feel that I have taken for granted everything that I have once loved. I feel that I have fallen into the trap of this materialistic world. I want things that can't love me in return. I stay away from people that do love me.

Have I really sold my soul to the devil?

What is the purpose of my existance in this earth?

Will I ever be able to find balance in my life?

What have I become?
