Maybe something will leave a scar, but it won't hurt you again after all. Don't worry, wait for time, get through this, and you will eventually become stronger than you are now.
If you have that idea to get rid of the shadow of the past, then you can do more happy things or volunteer, which will improve your psychological quality, and gradually you will let go and forget the past. It doesn't matter if you think about it occasionally, because it won't hurt you anymore. I believe you can solve this problem and keep a normal attitude!
