also if you are concerned re how you are feeling you can consult with your therapist.

i can't diagnose if you're becoming hypomanic but here are some good suggestions for coping with it:
Self-management
People who have experienced hypomania often know the signs of an approaching episode and can use a variety of strategies to prevent it from happening, such as getting plenty of sleep (this is particularly important), avoiding stimulants such as caffeine, and trying to induce a sense of calm (complementary therapies such as aromatherapy, yoga or meditation can help to achieve this). They also know to avoid making major decisions and to avoid risky behaviour such as spending sprees.
Talking treatments
Counselling and other talking therapies such as cognitive behaviour therapy may be useful in helping a person to recognise when hypomania is developing, and in keeping the symptoms under control, e.g. in helping them to resist the temptation to overspend or indulge in other types of risky behaviour.
