Lymphoma worry

I discovered a lump in my neck in September and recently had an ultrasound scan and biopsies. I’m anxiously awaiting the results and was wondering if anyone has any coping mechanisms they can recommend?  I’ve had a call from my GP to say that there were two enlarged lymph nodes that are suspicious and I should get results and an urgent appointment within 2 weeks. I’m only 6 days in to the wait and am afraid I may go mad - I feel panic and hysteria rise up in my throat when I go out and can’t wait to be back at home where I feel safer. Can anyone relate to this and if so, how can I get through the wait without completely melting down? Thanks in advance for any tips <3
