Throughout the day check in with how you are feeling, notice the emotions and what you are doing at the time. Try writing down the emotions you have felt on each occasion and rate how intensely you felt that emotion. After doing this for a few days, look over your notes and see if you can find any patterns or triggers that affect your mood either positively or negatively. Don’t try and stop yourself feeling the emotion, just be aware that in certain situations you are likely to feel happy or irritated.
