I cannot answer your first question: Is it possible to have bipolar disorder despite not having suffered any negative consequences? I would need more information. It would depend on what you consider to be negative consequences. Without knowing that information, I can only speculate.
It seems as though you perceive your symptoms as being advantageous. You are not alone with your beliefs. You may find the article, “Just Manic Enough: Seeking Perfect Entrepreneurs” (in The New York Times business section), to be interesting. It discusses a very similar point to the one that you are making. It essentially argues that in order to succeed as an entrepreneur, a certain amount of hypermania is necessary.
Many mental health professionals would disagree with the premise of that article. Many of them believe that mania, in all cases, is dangerous and would recommend psychological intervention. I can’t say with certainty but I believe that may be the opinion of your treatment team.
It is common for people with bipolar disorder to report that they like the feeling of mania. Tara Parker-Pope, who maintains the Well blog at The New York Times, featured a number of individuals who were willing to share their experiences with mania. One insightful quote came from Carter Goodwin, a 42-year-old artist with bipolar disorder, who said “I miss the mania…I love the mania. It feels so good to feel like I can do anything and like there is something really special about me. But it’s all chemical. It’s not true.”
Goodwin’s point is an important one. The mania makes him feel as though he has special powers and abilities but it’s a delusion. It’s not real and therefore has the potential to be harmful. To live in a world that is not based in reality is delusional.
Another complication of this situation is that you might have become accustomed to living with your symptoms and now they “seem” normal to you. You may now lack the ability to be objective about your symptoms. Thoughts and behaviors that seem normal to you may not seem normal to your treatment team.
You mentioned two additional issues regarding your treatment team. They do not focus on what you believe to be post-traumatic stress disorder symptoms (PTSD) and they want you to take a medication that you do not want to take. If you believe they are providing you with unsatisfactory service, then you might want to consider seeking a second opinion. If the second opinion is consistent with the first, it could be very telling. A second opinion could also provide information about how next to proceed.
If you’d like to write back and provide more information about how you define negative consequences, in reference to your first question, then I might be able to provide you with a more specific answer. I wish you the best. Please take care.
