Well done! Also keep in mind stress is to be understood, the cause of stress is to be abandoned, the ending of stress is to be achieved, the noble eightfold path it to be practiced- as per the dhammachakka sutta.
So always keep your radar on for stress,suffering,unpleasantness etc. When it arises, immediately note what the cause is - and get rid of it (the cause that is) from your mind right away. The work is internal, not external (we dont try to change the world- unless we really have to, but that wont take you to nibbana, just a somewhat more peaceful samsara- which is impermanent).
If you have found the right cause(s) - usually a craving or aversion or delusion- or a mix of these, you should experience 'personal 'nibbana' -a personal 'cooling' ..of the suffering and you returning to a state of peace.
Methods of removing craving, aversion and delusion are found here (and extremely important):http://www.accesstoinsight.org/tipitaka ... .than.html
Now what about unpleasantnes? While you are mindful of it, bear in mind that it will pass (vedananupassana). Then when your aversion to the unpleasantness has turned to equanimity, watch it actually changing and passing, with mindfulness.
What if there is no mental suffering or unpleasantness? Then understand that you are now experiencing samsara, which is impermanent and therefore unsatisfactory. The approach to this is different. The way to attain nibbana 'cooling' it to be mindful of its impermanence (ie vipassana) until the arising of sankhara stops for a brief moment and you are released from the suffering of samsara for a moment as well.

suffering from wrong view (existence of a self for example)- samma ditti
Suffering from thoughts of cruelty- samma sankhappa
suffering from breaking the precepts- the sila components of the noble eightfold path
suffering from other defilements- samma vayama.
then in moments when your mind is clear- go to satipatthana.
develop jhana - samma samadhi.
...then this is the last truth- the path you took to overcome your suffering.
