Hi all, first time post so here it goes.

Around 10-11 years ago when I was 19/20 I had a mole removed from my back that I thought nothing of as I was quite naive about skin cancer. Was told it was nothing to worry about, fast forward maybe 6-7 weeks still no news so I assumed it was good because there was no rush. I was called in and was told the Drs looking at it could not make there minds up, if it was put in front of 10 , 5 would say it's fine, 5 melanoma. So it was decided that I would have a WLE & SNL biopsy, thankfully both came back negative and I proceeded with my follow up skin checks. It was stage 1B. During this time I developed major health anxiety, playing with all my lymph nodes, self diagnosing myself through Dr google! I messed around with a node in my neck that has swollen up and was so afraid of cancer I put it off for maybe 12 months, finally got it removed and it was classed as reactive. 
Found a node in my groin that I probably touched 100 times per day, convinced it was lymphoma, again put off the Drs visit and when eventually came to it I was told it wasn't even swollen! I made a 2nd app within 2 weeks to double check. 
The anxiety seemed to stop a bit for a few years until I suddenly lost my father in law to a heart attack, this then sent me into a frenzy, convinced I was having heart issues I went for an ECG, again all fine. Now the last 2-3 weeks my anxiety seems to be back and the driver in it is my new found pride and joy, my 6 week old little girl! I've had a mole on my chest for as long as I can remember but I'm now convinced my melanoma is coming back and I'm dying :( sorry to sound so dramatic , I have a picture of it from 3 years ago and there is no change, although it is irregular in shape and 2 shades of brown, it's small and not raised. I'm really freaking out and have been on google day and night searching recurrent melanoma death rates and if I could have metastatic cancer without knowing. I've got a phone app with my GP on Wednesday that has asked for a picture of the mole I'm worried about, I'm afraid of what will be said and the thought of having a biopsy and awaiting results is making me feel ill.
