Nodule beside uvula...What is it? Why are all these things happening?

Yesterday I foud a small hard nodule "under the skinn" about 1/2 - 1 cm beside the uvula in the soft tissue of the pharyngopalatine arch. The nodule has av very solid consistense and is well defined "roundish". No change in color of the skin . Does not hurt to palpate and you can barely see it ( I looked with a flashlight). What can it be?

Posted this question at ehealtforum but don't think I will get any answers from there.

Getting more anxious and depressed. I know it is stupid to think the worst things will happen but since a couple of days I really find myself in a mood of resignation.
