Male 38yo

I have a 5mm raised common mole just above my left foot which has been there at least a decade. Last month when I got out of the shower I noticed it was bleeding. My skin around the area was extremely dry and tight and both feet had been itching profusely (I suspect because I'd been wearing socks in bed and they got really dry).  I had been scratching my foot to the point I caused some lesions that had previously been bleeding. 

Armed with this background info and a photo, my GP said it's probably just trauma but he'll book me a face to face appointment and if it looks normal before then, just cancel the appointment. This took 7 days but finally looked normal the day before my appointment so I cancelled (hopefully not something that will cost me my life), and breathed a sigh of relief. 
 

a few days later (about 3 weeks ago) I noticed on glancing at it that my mole looked somewhat redder and darker than before. If I press on it, it blanches (looks normal colour) then I release and a few seconds later it goes darker/redder again, indicating vascularity (some Googling on this makes me concerned it's blood vessels feeding something nasty).   Furthermore, in about the same time as it bled maybe a week or two earlier I started noticing a weird discomfort in my left groin or testicle area, I can't quite tell which. I can't feel any bumps where the lymph nodes are but it just feels odd, like a very dull ache - gentlemen, sort of like if an hour ago someone punched you down there and the pain has almost gone away, or say if you kind of squashed one of them.  Stupidly I didn't mention this at the time. Testicle itself feels fine.  This has me terrified that it's a melanoma that has already spread to my lymph nodes. 

Today I used an app called SkinVision and it says it's high risk and their faq says 1/3 true positive rate. And now I'm absolutely terrified!  Made another phone appointment but it's not until the 16th of April.  

Also the skin surface on the mole is very shiny/smooth/reflective. I don't know if just because it's newish skin, or another sign. 
 

what are the chances that it is still trauma and just still healing even after a month?  Is it normal for a mole to blanch like, ever, if it's not cancer?

Reading that a pop star my age is terminal didn't do my anxiety any favours. 
 

also how do you deal with the wait?  I'm thinking about it constantly, feeling depressed over it, trying not to get too close to people I may otherwise have an interest in as I don't want them to get attached to me only for me to die, etc.
