Thank you for your response.
It sounds like you have had mood swings, mostly depressed mood.
You may have Bipolar
disorder or manic-depressive disorder
. It causes mood swings that range from of the lows of depression to the highs of mania. When you become depressed, you may feel sad or hopeless and lose interest or pleasure in most activities. When your mood shifts in the other direction, you may feel euphoric and full of energy. Mood shifts may only occur only a few times a year, or as often as several times a day.
If you have Bipolar disorder, antidepressants may not work well on your condition.
Some medical condition may cause mood swings in you. So, you may need a physical check-up to detect and rule out any medical condition that may be causing mood swings in you.
I would advise you to see a psychologist or a psychiatrist for psychological assessment.
If you have bipolar disorder, you may need to work with a psychiatrist (M.D.) and a psychotherapist. Treatment for bipolar disorder consists of pharmacotherapy (by psychiatrist), individual psychotherapy (Cognitive-behavior therapy - CBT) or Interpersonal therapy (ITP) by a psychologist or psychotherapist), and group therapy or support group by a psychotherapist. Pharmacotherapy is a critical aspect of treatment. Individual psychotherapy will help you for support, ventilation of feelings, coping skills training, and direct advice. Group therapy is useful for you to address the issues – adherence to medication and therapy, regulation of self-esteem, and management of other psychosocial issues.
In addition, walking, jogging, yoga, swimming, aerobic exercise, biofeedback, acupuncture, nutrition, and massage therapy may be helpful to manage and improve your mood.
I hope you get well.
Please let me know if you have more questions or I have overlooked any. Warm regards,
