Out of control

I've just spent the better part of an hour detailing all the moments in my day that frustrated me and/or made me feel hopeless and helpless. As I would love to be a more positive person I will just say that I needed far too much help today for my liking and, considering that I nearly fainted while out shopping, I'm going to start looking after myself a little better from now on. How can I do this? Well physically I can eat well and drink enough water, and do my fitness more regularly, and emotionally I can set small goals for myself and improve my self-confidence. It sounds so easy!
