Its very easy to say you are stressed out, but I think it really hit me what stress was when I was in class last week. Apparently stress causes your body to go into a flight-fight mode and if you do not have an outlet for this stress, you can cause serious problems with your immune system. There are also symptoms of becoming stressed like headaches, upset stomachs, hyper tension. Its no wonder so many working parents can acheive all that they do.
