Lump in groin :(


So I have this lump in my groin that I’m pretty sure has been there a long long time. Last night in a bout of anxiety I checked it. It’s about the size of a soft kidney stone and is situated in my groin. I have booked a doctors appointment but can’t face going to work because my anxiety is so awful. Am convinced I have cancer. Please may anyone reassure me.

I’m very thin and apparently sometimes this makes feeling lymph nodes easier?
