I wanted to touch base on your feelings of not being happy because you are using every moment of your time to achieve your goal, not allowing any space for anything else in your life.

Happiness comes from within ourselves. Even our Constitution does not guarantee happiness. In fact the exact words say "to pursue happiness". Your situation of feeling unhappy comes from your view of your current life. You are comparing your life through your view what you think of others life and that comparison is surface only reality. You have no idea what rests in the heart of someone else. Perhaps they are feeling a greater pain than you and are masking this pain through living a jolly exterior hiding their truth? Perhaps you walk by a young man each day who never had the opportunity of going to collage at all for reasons only they can say? Perhaps you get into thoughts of unhappiness out of habit and look for things to justify your unhappiness?

But no where do I see Gods hand in why you are unhappy. Beiing happy is a frame of thought.. While one person complains that the rain doesn't ever stop, there is another that rejoices that crops will finally grow and be bountiful thanking God for fulfilling this need. Its all in the perspective we choose to look at life. Thoughts control moods far more than anything else.
