Mindfulness in Everyday Activity I have been practicing meditation, reading and listening to Buddhist teachings and I undertake the five precepts for about year now. This is the first time that I actually ask a question about my practice. I meditate every morning and then during my daily activities I try to be mindful watching the physical and mental phenomena. 

I can be mindful quite well but as soon as I experience an unpleasant mental state such embarrassment or awkwardness fear and aversion come up and I feel kind of lost. It is like I forget what to do and I am not able to be mindful anymore. This happens even if I am well prepared to experience an unpleasant mental state. It happens when people are around and very fast too and even if I am not scared to experiencing them when they come up, it seems that I lose track and I forget everything. So what can I do in these situations?

Sorry for my English. I hope that this make sense.
Thanks for your time, may all beings be happy and free from suffering.
First, congratulations on your year of practice. Sometimes we overlook the most basic principles of our practice, as such I am referring to the first noble truth: there is suffering. Note that it is not stated, "I suffer". By being stated this way it can be understood that suffering is not, "yours" or "mine". As opposed to viewing these experiences as, "I am embarrassed" or "I am feeling awkward" reflect upon these moments as, "there is embarrassment" or "there is fear". Know they are not yours but emotions that result from a particular experience. Also, bear in mind that as you reflect upon this experience you are being mindful and in the moment (meditating). Being mindful does not in itself guarantee happiness. Mindfulness combined with skillfulness will move you toward your goal. These principles are found in the Eightfold Noble path. Try noting your experience. Saying to yourself for example, "fear" or "embarrassed" as you would during formal or seated meditation, allowing for the physical response to dissipate.  

"To let go of suffering, we have to admit it into consciousness. But the admission in Buddhist meditation is not from a position of: "I am suffering" but rather, "There is the presence of suffering" because we are not trying to identify with the problem but simply acknowledge that there is one." - Ajahn Sumedho
