again most of the symptoms the posters are describing are symptoms of depression. Please look it up on the American Psychological ***. site, pretty good descriptions of depression. There are different kinds of depression but the ads on TV are describing clinical depression, the most severe form.
That said many medications can also cause the "brain fog", lack of motivation etc. so it becomes very difficult to differentiate between underlying depression and/or side effects of meds. Also depression is a common result of coping with a chronic illness.
The best answer would be to try some therapy and see if you feel/funtion better. Nothing to lose.
The recent "bailout" bill also contained a bill to make mental health insurance benefits the same as physical health, same co-pays, no restriction on number of session ,same deductible. soon mental health treatment will be available for everyone with insurance.
