If the events keep recurring in your head, and they're intrusive, there's something that isn't fleshed out. That needs to be reconciled. Start by writing out these dreadful moments, with exacting detail. Look up dates. Talk about tones of voices. Where were you at? What was everyone wearing. Minute detail. What happened. What do you wish would have occurred differently? You need to reconcile all of the details, so that your brain can appropriately lay them to rest and move forward. The past authoring program may be of help. "It would be particularly useful to complete the Past Authoring Program if you have memories that are more than about eighteen months old that still intrude upon your thoughts, or that still evoke emotion such as fear, regret, shame or confusion. If this is happening, it means that your mind has not yet been able to fully process your past experiences, and that the brain areas associated with negative emotion still regard the past events in question as unresolved threats. This is not good, because your brain reacts to unresolved threats with emergency physiological preparation, including the production of stress hormones such as cortisol that can be very toxic when chronically elevated" https://www.selfauthoring.com/past-authoring https://www.selfauthoring.com/past-authoring
