I am so sorry to hear that you were attacked like that. How horrible. I appreciate you sharing this with me.
It is good you decided to share this with your boyfriend and your therapist too. One of the best things you can do is to get as much support around yourself as you can. Until you feel better, rely on others to help you through.
Another important thing to remember is that this was not your fault. No matter when you took the trash out, you did not deserve to have this happen to you. Rape is never the survivors fault. It is always the perpetrators fault. Blaming yourself is only going to hurt you. Working through your need to self blame is part of your recovery. Go easy on yourself and lean on others to help you.
It is easy to go into yourself and become upset and depressed. But if you can, try to reach out. Here are some resources to help you:
It can help you to connect to others who understand what you have been through and help you heal.
