Thank you for your reply.
It sounds like he exhibits depressed mood and mood swings.
His words are indicative of feelings of hopelessness. That's a sign of depression. He doesn't fight for his daughter as he may be depressed and apathetic. Also, he seems to have mood swings that may be causing problems in your relationship.
It's possible that he may have Bipolar
disorder if you have "wild" mood swings. Bipolar disorder is dysregulation of mood, attention and energy.
Bipolar disorder is associated with mood swings that range from the lows of depression to the highs of mania. When a person becomes depressed, he/she may feel sad
or hopeless and lose interest or pleasure in many activities. When a person's mood shifts in the other direction, her or she may feel euphoric and full of energy. Mood shifts may occur only a few times a year, or as often as several times a day.
It's important for him to find out whether he has major depression or Bipolar disorder.
If he has severe mood swings, he may need to see a psychiatrist or a psychologist for assessment/testing.
He may benefit from continuing weekly psychotherapy whether he has depression, anxiety
, dysthymic disorder or Bipolar disorder.
Let me explain about depression: Depression can disrupt the nerve impulses that carry a constant stream of orders from the brain to the muscles. When the depressed brain slows down, so do the signals to all parts of body. Symptoms of anxiety overlap those of depression. Depression affects MEMORY, problem-solving ability, language, perception and is accompanied by nervous tension, anxiety, and profound fatigue. It can generate pain and aches. Medical reasons for Depression may include thyroid hormone abnormality, Vitamin B12 Deficiency, Chronic pain, Stroke
’s disease to name a few. Malnutrition/brain damage can dull mood further. Excessive alcohol use may aggravate depression. Some medication can cause or contribute to depression. Your doctor should know all the medication that you are taking.
If he has Bipolar disorder, he may need to continue working with psychiatrist (M.D.) and psychotherapist. Treatment consists of pharmacotherapy (by psychiatrist), individual psychotherapy (Cognitive-behavior therapy - CBT) or Interpersonal therapy (ITP) by a licensed psychologist or psychotherapist), and group therapy or support group by a psychotherapist.
Please feel free to ask me a question if you have even after you get this answer.
