Hi Cecilia,
Don't give up. Day 1 is depressing, I'm only on day 2 and I felt the same yesterday. Someone could have handed me a winning lotto ticket and it couldn't have pulled me out of the dread I felt. If you find posts that bring you down, move on to another one that inspires you. We can only change ourselves, another person or a website can't do it for us. You did this before for 19 days so you can do it again. I know how you feel, because I am there too. Let's do this together and experience life in 2015. What's the alternative?
