Name's Lilyrose, thirteen. I have been through a lot. Verbal abuse, sexual harassment, trauma, anxiety, trust issues, abandonment, and depression. My therapist began talking about a very triggering topic and I just burst out crying. She wrapped her arm around me and told me it was okay to cry. I felt so weird for crying in front of her. It has been a whole year after my traumatic experiance. I didn't realize I was still this hurt. I don't want to write it or text it to her. It needs to come from my own mouth. It has been a whole year, if I am not able to talk about it now then I don't think I ever will. I just can't get the words out, it doesn't feel right
