Driving myself crazy with health anxiety. I noticed last week I have a hard lymph node in my neck. I saw my gp who said it's a reactive lymph node, probably due to an infection but that I should go back in 2 or 3 weeks if it hasn't gone. Frankly I am terrified - I seem to have lost all perspective. I am not aware of having had an infection and the fact that it's hard and painless is really playing on my mind. Am even thinking of going back to the gp tomorrow but I 'm worried about that too. Please, anyone, some positivity?
