Thanks you for your query.
You have described as experiencing extremes of mood- elation on one hand and depression
on the other.These are two poles of mood extremities and when they keep swinging back and forth or occur together(what we call a mixed state) causing a disruption in normal functioning it is an indication of Bipolar Mood Disorder
.Suicidal urges commonly accompany the depressive phase as is evident in your case.
is usually treated with a combination of medications of which a Mood Stabilizer
plays an important role in controlling the symptoms as well as in preventing further episodes.
Hence it is imperative that you consult your doctor at the earliest and be started on the appropriate medications.It is also essential that you continue maintenance medications even after your symptoms remit in order to prevent recurrences.You will also be educated on measures such as ensuring good sleep as disruption of biological rhythms might also trigger an episode.
Wishing you the best in health and life
