If you struggle with anything rather is an illness, a sickness, a birth defect, a struggle, anything that you feel makes you weak, that makes you question, "God, why me?" Believe me, there is a reason and He never meant for it to be a punishment, to destroy us, to hurt us, instead he did it because he knew it was going to be the only way that we would truly surrender and believe that he will conquer it all and that, "There is power, in the Name of Jesus," and that from that will comes: joy, happiness, trust, love, healing and most importantly Hope.
Be Shameless in feeling defeated if it's God you are trying to battle, the only difference is that it's a great defeat with a wonderful reward, God is Love and that is your reward.
