Swollen lymph node on right neck

I had recently posted a question about a swollen lymph node on right side of neck it has been here for a year it is not painful but does cause slight difference in hearing, i had an mri done 3 weeks ago, I can not find a doctor to see, the clinic said it would take four months to be seen, although they are telling me I need to be seen as soon as possible should I seek other help, is this something I should worry about? Other symptoms tired, weightloss, my mood is all out of wack. Please reply
