Secondly, get active!
Human beings were not meant to be sedentary, alot of negatives both physical and mental come to us when we don't move and do stuff because, whether you believe in evolution or intelligent design, we were made to do work. We weren't quite meant to fly, but we were given legs to walk and run, muscles to lift heavy stuff, and arms to reach and climb.
When you exercise, your mind become more clear, focused, and sharp, your body releases endorphines and hormones to return balance and peace to an over-stressed mind. You wake up feeling energized, alive, and hungry for life. The more you do, the more energy you have to do more stuff and the easier everything from walkng up steps to lifting a bad of groceries becomes.
It is key for all of us to find a gym, whether its in a backyard, a friends garage, or a multimillion dollar facility (mine was the lake I grew to love). Get out and walk in the early morning light, hear the sounds of a world waking up to the rising sun, or go for an easy jog around the block. A month in the gym will realign your entire perspective (the first few weeks seem rough but only because the mind's self-conscious tendencies get in the way of a good workout) and a mere week of running will help you throw off negatives like a moving meditation. The mind-body connection is all too important for one to to allow oneself to reject physical activity.
Sorry if all this is a little much, changing your self-image and fostering love is a long, slow, and sometimes difficult process. It is easy to get discouraged, which is why mankind has evolved to become communal, so we could encourage, inspire, and push each other to succeed. Change is often the hardest thing to someone who is set in their ways but again, without challange and strife there is no evolution. It takes grit, toughness, and determination, all of which can only be learned from one's own Self.
