How to deal with lymphnode anxiety?

About a week ago I was touching my neck to massage because I had a horrible headache.

And I found something I didn’t expect - an enlarged lymph node on the right side of my neck. (it’s called the cervical I think)

It’s small, I would say the size of a pea and feels like it’s movable I think. You can’t see it in the mirror, only can feel it when I touch it.

What’s bothering me is that I don’t have any infections as I don’t feel anything.

I have lost weight but it’s because I was eating little, plus finally got my thyroid meds which fasten the metabolism.

But my mind is still obsessing over the fact that I have a small lump in my neck and I’ve lost weight.

It’s been a week since I noticed it and I have a phone appt with my GP on Monday.

I’m terrified of the waiting itself, as it’s Christmas next week + covid, it’ll take so long until doctors will do something.

I tried convince myself that it’s nothing, reading other people’s post in this sub related to lymphnodes, but I still am scared that mine is something bad, and all I want to do is cry and hope it’s just a benign node.

Sorry for venting, but how does one deal with this anxietyyy
