forget

okay non existent people I talk to when I am bored/ needing to talk,
I have a question.

Is it possible to erase something from your memory completely?

like I know you can forget things, you forget where you were, what you were wearing, what you ate, etc. But you forget those things because they aren't significant. Then why can we not forget things that  happen to us or terrible life experiences. Why do we have the ability to forget meaningless things, but we cant forget things that have scarred us,

I know that they shape who you are, but not everything shapes you into who you are. Some things are just scars that still hurt when you touch them. Those things don't shape you. If anything they harm you so why are we allowed to remember the things that leave scars, but the small and simple things get erased...

Well I guess that is the answer. Small cuts and bruises fade away really fast, but the deep cuts stay a while. Eventually they might fade, but there will always be a small mark that shows where the cut was.  I wish they could disappear completely. Sometimes I feel myself slip back into a place where I feel like my world is crumbling. It's sad to say, but I sometimes replay my fiance breaking up with me. This happened a while ago, but now we are fine (obviously) because we are getting married. But I sometimes replay it in my mind and it brings me back to how that felt. I can still hear him talking and I can still feel the cold wind that was blowing down my neck. I remember seeing his eyes shining from the street light. And I remember that hug that I thought would be the last. Every time I think about it the hole in my chest goes right back to where it was. I know everything is okay now, but that pain does not erase. Well at least not easily.

Why do I need to remember that pain? What use is that? It just puts me in a terrible place and can honestly ruin my whole day.

I don't know maybe I am just crazy

So non existent people, why cant I forget things?
