I need some advice from people who have dealt with psychiatrists and medical professionals and understand the politics and culture surrounding it. Here is my situation. I have been experiencing a lot of mental health issues. I have struggled with eating disorders, depression, self harm, anxiety, and when put on fluoxetine (prozac) I had a hypomanic reaction. This led me to being evaluated by my university's psychiatrist specifically for bipolar disorder. I am 19. I know from my personal experience that I have intense mood swings and obviously many disordered behaviors, and I once mentioned to my therapist that I suspect I may have bipolar disorder or another similar type of disorder.
The psychiatrist basically told me that I was only experiencing a drug reaction and that I have a lifelong history of suffering with depression and am just an "intensely emotional person." He said that because I am only 19 and have not had such an extreme manic state while not on prescriptions, I am not bipolar. He told me my intense mood swings are just a part of my personality. However, because of the disordered behaviors that I deal with and the fact that these behaviors have drastically increased in the past year or two, which is the typical age that mental health issues begin to reveal themselves, I am having a hard time writing off my problems as just 'being emotional.' Despite being in therapy and actively trying to stabilize my mood, they are still significantly affecting my life. I was quite honestly surprised by his attitude- he said that I didn't need to be medicated but that I "would probably benefit from continuing therapy." Considering that I often feel out of control and in danger from myself, I found this to be an oddly lighthearted way of looking at the situation.
He said that bipolar disorder manifests itself between the ages of 17-35 so it is too early to tell whether I am bipolar. The thing I'm struggling with is that I know many people my age and younger are diagnosed with bipolar disorder, so my question for the community is this: how beneficial (in your personal opinions) would it be for me to seek out a different psychiatrist and get a second opinion? Is there some kind of general reluctance to diagnose the disorder? Would other psychiatrists also consider my behaviors not too extreme? I have little experience with the mental health system so I don't know how to navigate it. Any opinions or advice would be appreciated.
