If anger is the only symptom, I would start with Anger Management therapy. Anger alone can cause lack of control and psychotic events. My bipolar is more rapid thoughts and emotions. Confusion that leads to depression. All emotions are involved. I can be ecstatic, sad, angry, high-self esteem, low self-esteem, anything could happen. I am just learning more about my disorder, but I would not jump to a chemical imbalance too fast. Do you drink, use pot or other drugs? Do you have a lot of stress, or unresolved resentments? CBT helps my addiction and bipolar, it helps me keep control of my behavior, not my emotions, but I hurt people less. There are tools to help you deal with your anger, I would go from there.
I am often depressed. I am CONSTANTLY stressed to the point to where i scream and yell so much my stomach will hurt and i get nauseous. I grew up listening to arguing and fighting constantly. Constantly put down by my mom and I eventually turned to drinking everyday with my friends. I no longer drink and haven't in over a year but still have this problem. I am now 6 mnths pregnant, and the hormone changes add to the anger but also reminds me to try and keep it under control for my baby. When I told my family I was pregnant, 2 weeks later my mom left my dad and she's been back n forth home and with her "boyfriend". Which contributes to my problem.
I don't drink or do drugs, I just feel like I'm driving myself insane.
Honestly, it doesn't sound like bipolar, clinical depression maybe, but I wouldn't jump to that conclusion. I grew up in a pretty rough environment. Many things hurt me. It was to much to handle, so I stopped feeling anything but anger. I have two kids, so I know how it is, from watching my wife. Your emotions are off the chart. if you stuff feelings, I can totally see your fits being a release. I would go to therapy, you may be able to balance out by understanding yourself better, learning triggers and skills to use when they come. thought it would be a joke, but I was pleasantly surprised. Glad you don't drink or do drugs, you would have to deal with that first. There's no way to diagnose on the Internet, I'm nowhere close to being qualified, but you are not leading me to believe you are bipolar, if so, not too severe. Just an opinion from very little knowledge about you. You haven't described the mania, as far as I can tell. Obsession maybe, compulsion maybe, but the switch from manic to depression feels like more than anger and frustration. I hope you find peace, congrats on the new family member. I waited way to long to deal with my childhood, life experiences, and mental health. Keep searching for answers, you will find them.
Also, my bipolar does not feel like I am driving myself insane, it's more mike being possessed, I can be feeling good and not worried about anything and still slip into a cycle.
While this isn't a personalized answer, based on what you have written you wouldn't meet DSM criteria for bipolar disorder. If anything, you may have some level of depression/ depressive symptoms, maybe some anxiety/ oppositional defiant disorder type symptoms. But again, it's hard to tell from what you have written. If you are really concerned or feel like it is leading to a poor quality of life, go see a doctor. In my opinion (not a doctor), I don't think you have BD based on what you wrote.
In my opinion the best place to start is by seeing a psychiatrist. They can help you figure this out and determine what course of action to take. They will steer you in the right direction for help if you don't have a illness. They will ask lots of questions from childhood to adult (which would include how you were before you got pregnant). Go prepared with a notebook to help you relay the information.
I would recommend talking to a doctor about your issues. He or she can point you in the right direction, either a therapist or psychiatrist.
Congrats to you on trying to figure things out! Next step ? Speak to a counselor /therapist and het a correct diagnosis.,you can also speak to your family doctor and he can point you in the right direction. It sounds like maybe anger management would be very beneficial to you. Best of luck.
