Introduction- Hodgkin's Lymphoma

Hi All,
I just joined this site after I called a cancer help hotline. My name is Brianna, I'm 22 years old and I was diagnosed with Hodgkin's Lymphoma about 2 and a half months ago. I completed 2 cycles of chemo so far. I have a pet scan tomorrow that I'm very nervous about as it determines my progress and the fate of my treatment. Although I've been handling this quite well, in the recent weeks I've been showing signs of anxiety and depression. I'm doing my best to stay positive but sometimes I find it incapable to have fun anymore. Am I alone in this? Looking for people to share their stories who are going through something similar.
