Could this have been an Anxiety Attack?

I'm a 20 yr old male. Recently I have been doing a little to much deep thinking about my life and have fallen into a slight depression. I have been going through chemotherapy for hodgkins disease so I have been home doing nothing with my life for the past few months. My depression has NOTHING to do with the cancer as I know I will be fine, the chemotherapy is working very well. But since ive been spending all this time alone healing I recently felt that I have no motivation for life anymore. What scared me the most was the other night I had what I believe to be a anxiety attack of some sort, I couldn't sleep, I couldn't concentrate, I woke my parents up just to speak with them. I guess the fear I was having is that I would have this feeling of emptiness for the rest of my life and that it would get worse I have. NEVER been like this is my life. I recently applied for a job so I could keep my mind occupied so I pray to god that this problem is only temporary and because of my boredom at home. What do you think?
