Magic is inside you, outside you. If you are real, then magic is too. In order for magic to work for you, that understanding has to be there first.
Get to know yourself. Looking at only what is going on outside you and feeling miserable with your life? What is inside you? Learn to meditate, to not think. Read about deities and learn more about the one(s) you identify with.
Find some books on meditation and brainwaves. Find yourself a teacher, someone who seems to "get it." A good teacher is not necessarily someone who is of a magical leaning, just someone who sees that you are struggling and is helpful.
And please quit whining. Even if all the swirling thoughts are kept inside, what you think (or don't think) is what you are. What do you want to be? That's what you need to be thinking about and learning about.
