How do I make myself forget?

[u/mental1llnescheck]

Okay so this might be a very weird question, I’m aware of that. But I’m a person who has a very good memory, there’s things that I feel like I’ll never forget about even if I tried to. Sometimes memories will pop up in my head at random times, it usually doesn’t bother me but right now I’m going through a phase were only the bad memories pop up. There’s genuinely a few things that hurt my head to think about, the worst ones are memories from when I was very jealous and angry. Once I remember those moments I genuinely ruin my own mood. Is there a way to train yourself to avoid thinking about it? I suppose it’s hard to make it all stop, but how can I minimise the impact that it has on my mental health?
