According to Pope John Paul II, "the worst prison would be a closed heart". True love has no beginning and true love has no end. You do not need to learn how to love because you were born to love. You are not the only one with troubles. You are not the only person with pain. I am poor and there is no doubt I am a poor man but I consider myself very lucky because there are so many rich people who aren't happy despite all their wealth. At least I have both eyes and I can see. I have both ears and I do hear. I have all my limbs and I do walk without a walking stick. A friend of mine just lost one limb in an accident. I have another friend who became blind at the age 18. You are not the only person with problems so don't worry too much. Just open up your heart and Love.
