Nobody needs to know you get a little confidential advice.
Let me reassure you, many of my patients have good outcomes but this is a lifelong illness. The key is to develop a good working relationship with your doctor and communicate clearly. Journaling symptoms and side effects can help direct your treatment and community mental health support groups are really wonderful resources. I wish you the best.
NIH, National Institute of Health and American Psychiatric Association are some good resources.
There are a multitude of possibilities including psychiatric, such as Depression or Dementia, which can be reversible early on if caused by nutritional deficiencies such as B12. There are many neurological and medical causes which any of the named practitioners can screen for: thyroid, cancer, insomnia, strokes, medications especially etc. I would start with my PCP, get some blood work and/or medical evaluations and mental health screening, then get appropriate referrals.
However there could be other explanations. I would suggest you speak to your regular doctor who can do some screening and refer you to appropriate professionals (psychologist, psychiatrist or others) indicated.
Your doctor should also check for obvious medical causes such as thyroid disease, nutrition or even cancers according to your demographics or risk factors. Regardless of the etiology, there is a lot of wonderful positive mindedness research to show its benefits in all aspects of health, mental & physical, and in coping with daily life stressors. You can work on this on your own, not to discourage psychotherapy. NY Times magazine had a special edition on mental wellness this summer and a lovely review of resilience and how anybody can learn positive mindedness, regardless of personality or traumas. You could easily google up a plethora of articles on this. Nevertheless, you should still go and discuss this with your primary doctor.
I wish you well,
Dr Lewis, MD Psychiatrist
