Swollen lymph nodes

I’ve had painful, swollen lymph nodes for about a month now. Some days they hurt, a day or 2 pass and they’re gone, and then they’re back.

I don’t have any infection but I might have allergies. Not too sure though.

I’ve lost some weight BUT it’s not unexplained as I have hardly been eating due to stress and anxiety.

Of course, I googled why my lymph nodes are swollen for so long and my lymphoma came up:

I looked at the symptoms and then started over thinking everything. For ex; yes I’ve been more tired lately and yes I’ve lost some weight.etc

So now I’m freaking out more.

I had routine blood work done 3 months ago for a physical and my blood work came back normal.

So now I’m freaking out. Called the doc already, and they have something available in 3 weeks. Until then, how can I keep my sanity,
