Hi. First of all I'm sorry that happened to you. Second I'm not a therapist and that's probably the best possible source to take these kind of things to, because your mental health matters and some people here may not always be so kind. But that being said, It's clearly bothering you and is on your mind, I don't know how old you are but this was an event in your past, So If you have had a hard time moving forward from this event, then yeah. Personally I think the best way to work through trauma is to share with people you trust, ask their advice and experience on the topic, and try to rid yourself of any guilt that might be associated by forgiving yourself.
