Perhaps if you could add a little more context to your situation, have you had any recent infections which might have caused your lymph nodes to swell, you mention tonsils, are they chronically infected ? As well i presume the lymph nodes you are talking about are in the upper neck area which is a good thing, namely these nodes react to infections situated in nasopharynx, oropharynx and laryngophanrynx along with any possible gum, teeth, etc. infections.
Anyhow, what helps me get my mind off things is work, in general keeping busy, and i know its easier sadi than done but i'd try to constantly do something until the follow up. All the best :)
