Swollen lymph node

Hi all,

Just been referred for a biopsy of a swollen lymph node in my neck. It doesn't hurt or move.  Been there about 2 months.  Fairly large about the size of finger nail. Since the doctor checked me and advised biopsy i can't stop thinking of anything else. Biopsy in 10 days. Extremely anxious now. Trying to keep busy and not check Google too much. Some advise would be appreciated.
