Cindy Sue,

That would have spoiled my mood too! Unfortunately when we are in a sensitive state i.e. depressed, people do tend to push our buttons easier than usual. There will always be people who will try and destroy your mood if you are actually feeling good. Some people do it on purpose (like my mother), others do it unconsciously, (but it doesn't hurt less). I think the problem is that the smallest comment throws us into this downward spiral of negative thoughts. Hopefully this is what the program is supposed to help with. It takes time to start challenging those negative thoughts. If you don't have a million negative things to say to yourself to prove your mother-in-law's comment is true, your mood won't be affected that badly. I am on session 8 and am starting to challenge those core beliefs that we bring up everytime someone says something that hurts us. It is a hectic process but think it makes sense that most of negative spirals come from those core beliefs that we are not loved or not good enough. If we can just replace those with postive thoughts, other people's comments would not hurt us so much because we won't believe what they say. Hang in there- the fact that you are planning pleasant activites for yourself is a great start, you should be proud of yourself!
