It doesn't seem like you are describing bipolar symptoms.
Bipolar Disorder, formally called Maniac Depressive Disorder (MAD), is a mental health condition that causes extreme mood swings that include emotional highs (mania or hypomania) and lows (depression). When your mood shifts to mania or hypomania (less extreme than mania), you may feel euphoric, full of energy or unusually irritable. When you become depressed, you may feel sad or hopeless and lose interest or pleasure in most activities. These mood swings can affect sleep, energy, activity, judgment, behavior and the ability to think clearly.
Individuals can relive past traumatic events. The unused excess stress energy is stored within the muscles and nervous system. When the stored energy reaches the body’s capacity, it can trigger a massive uncontrolled release producing the mania or hypomania condition. And one of the reasons is that when you do these kinds of reliving or flashbacks, there's a tremendous release of adrenaline. There's also a release of endorphins, which is the brain's internal opiate system. In animals, these endorphins allow the prey to go into a state of shock-analgesia and not feel the pain of being torn apart. When people relive the trauma, they recreate a similar neurochemical system that occurred at the time of the original trauma, the release of adrenaline and endorphins. Now, adrenaline is addictive, it is like getting a speed high. And they get addicted not only to the adrenaline but to the endorphins; it's like having a drug cocktail of amphetamines and morphine. And after the stored stress energy is depleted, their body crashes into depressed state. The effects of coming down from a speed high are: feeling restless, irritable and anxious, aggression that may lead to violence, tension, radical mood swings, depression, paranoia, lethargy, and total exhaustion.
