This is kind of a long one but here we go! 
my dad passed away from throat cancer that moved to his lungs in January, last may he had a lump on the side of his neck and a prolonged sore throat and he got diagnosed, in January my wisdom teeth got infected and the lymph node under my left jaw became hard and even after removal of the teeth and healing it never went away. I went for blood tests and an ultrasound scan and it came back normal this was over 4 months where I was completely freaking out anxiety so bad I couldn’t do anything, the ultrasound coming back fine gave me a lot of pace of mind and I started therapy for grief and health anxiety as I’ve lost both my parents in the last 4 years at 23 so there’s been a lot going on stress wise for me. I’ve been getting persistent sore throats and illnesses since and I am currently sick and another lymph node has come up hard on the same side as well as ear pain in that side body aches and breathlessness (although I don’t know if this is anxiety related) I’ve had another blood test that is normal but I can’t shake the constant cancer anxiety and just wondered if anyone else had had similar problems and got any answers for what it could be. I’ve been to the doctors so much I just think they fob me off as an overly anxious person but it really feels like there’s something wrong.
