It's important to remember that diagnosing mental health conditions requires a qualified professional, and I'm unable to provide specific diagnoses. However, I can offer some general observations that might be helpful.
Mood swings: Rapid mood swings that go from 0-100 within a short time could be indicative of various conditions or emotional states. It could be related to stress, unresolved emotional issues, or even underlying mental health conditions.
Unresolved emotional issues: Sometimes, individuals may have unresolved emotional issues from their past that can affect their current behavior. These issues could stem from childhood experiences or previous relationships, including parental relationships.
Anger issues: The sudden mood swings and going from calm to angry could be a sign of anger management issues or difficulties in processing and expressing emotions in a healthy way.
Bipolar disorder: While I cannot diagnose anyone, bipolar disorder is characterized by mood swings that fluctuate between depressive and manic episodes. These mood swings can be quite intense and disruptive.
Parental relationships: Parental relationships can have a significant impact on a person's emotional and psychological development. Unresolved "mommy issues" or issues related to one's relationship with their parents can influence how they interact with others, including their own children and partners.
It's crucial to remember that every individual is unique, and their behavior might have multiple contributing factors. If you are concerned about your kids' father's behavior, it might be helpful to encourage him to seek support from a mental health professional who can conduct a proper evaluation and provide guidance.
As for your own feelings of confusion and anger, it's understandable that dealing with such behavior can be challenging. It might be beneficial for you to seek support as well, either through individual therapy or support groups, to help you process your emotions and cope with the situation in a healthy way.
In any case, open and compassionate communication can be valuable. If it's safe to do so, consider having a calm and non-confrontational conversation with him about his behavior and how it's affecting you and the children. Sometimes, people may not be aware of the impact of their actions on others.
Remember that professional help is essential for addressing mental health concerns, and self-care is vital for your own well-being too.
