This is my summation of my research, and some personal opinions gleaned from a lifetime of mental illness:
Due to the length of this treatise, I am skipping the different types of psychotherapy and just saying that your therapist and your psychiatrist should communicate and be on the same page. As for the patient. Complying with treatment including psychotherapy is key to recovery or management, whichever you prefer. Also, if you are going through a tough life event, it is a good time to talk to your doctors about your medication needs and you therapy needs. You may need to add a medication or increase you already take, and you may need to see your therapist more frequently until you feel that you are safe, and can handle the situation.
In closing, Bipolar Disorder in all its various forms, manifestations and severity of symptoms is a rollercoaster ride. I tend to compare calm times to being on a long frequency sine wave where you rock gently through the ups and downs, and episodes both depressed and manic as being on the Richter scale. Then you are like an earthquake, and you never know what devastation you will leave in your wake. Hopefully, you never go higher than a 2.0 earthquake because then real damage can be done. Having Bipolar Disorder, in my opinion, requires a level of inner strength that is difficult to achieve because you will lose friends, you will lose husbands and wives, lovers and partners, jobs, and a sense of who you once were. You will question your self-worth, and your worth to other people. It is a devastating disease. It takes and takes, but will never give back. That you have to learn how to do on your own. It is a very needy disease that wears out everyone including the afflicted person. Even if you have the best doctors, and you have the disorder mostly managed, it is usually at a great cost to a lot of people including you. It can be a very lonely illness. But, this is not to say that it is a hopeless situation. You can manage it, you can find friends who will understand or will be willing to learn about it, you can find partners that are understanding that it’s not you that is acting out of sorts, it is the disorder. It is possible to rebuild your life with sympathetic people who will be there when you really need them, and they will understand that you are going through a rough patch, and need help. So, all is not lost as I once thought, and I would imagine other people have felt upon being diagnosed. If you choose to educate yourself about the whole thing, medication, therapy, mood swings, etc. you will know what you are fighting, and you can get the better of it.
