Congratulations on getting through the week, I know this week has not been easy for you, and today must have been a difficult day for you. But you got through it and I am very proud of you taking small steps on your road to treatment. It will be a long journey, but you are very strong and you have a good support structure of friends by your side, which will help you immensely.
What you are describing with the joggers is called hyper-vigilance, this is where you are always on edge and very tense and react to every external stimuli that causes an overexageration reaction. This is related to anxiety
and PTSD. But you are right by looking at the positive and saying that it was good that you went out.
Sometimes victims will remember more of the incident as time goes on because the trauma of the incident is starting to allow you access to those memories. I am assuming that you mean you are not sure if you want to tell the police about these new memories that you are having, when you say them. I understand that you do not want to tell the police about these new memories because that can re-traumatize you and bring you back to the incident that started this, but I think it would be important to tell them and give them all the information possible to convict him. Now the extra information may or may not help with their investigation and prosecution, but I think its important for you not to keep it in, for your owns psychological health, and also for police to decide what may or may not be important for their case.
When these new memories come back, remember to focus on the present and focus on not what happened in the past, but you are going to become and not let this define you. Remember you are Lauren and you are someone that can decide their own future, you have more control than you think. You keep focusing on the present and how you are going to become stronger from this, will make those memories not as traumatic to you because you will realize that is not you now and that while you went through a traumatic event, you do not have to be traumatized now.
I wish you the best of luck Lauren and I hope you continue to see lots of progress during your second week because I have seen a lot of progress during your first week :)
