You're not giving yourself enough credit! I think your thoughts are clouded right now and they are what are making you upset. You may want to look into CBT as it saved my life and I think it may be helpful to you too. I just sent a more detailed reply about CBT to Hunter01's post if you're interested. In the meantime try give yourself more credit and focus on what you have done instead of what you have not done.

P.S. I like your tag line as it is so true.
