Hi Gerrymac,
Firstly - everything you are feeling and experiencing is totally understandable and NORMAL for anyone in your position.
I am sorry you have had the result back of melanoma; but so pleased you have found this forum and managed to put your fears down in writing. No apologies are needed, the more you can talk about this shock the easier (I'm not sure thats the right word!

) it will be for you to deal with it. It is a terrible blow to have an unfounded fear realised, thank goodness you pressed on for removal with your doctor.
Dont worry about appearing an idiot pestering the receptionist - the fact is they put the phone down and can forget all about it, they go home at 5pm - but for you the constant worry is disabling and draining.
A wider excision is the normal route to go, it is carried out to hopefully remove all rouge cells, usually followed by a skin graft. After this usually 3 monthly check-ups are carried out by a consultant at the hospital with you checking yourself in between times.
You're no over-reacting, nor blowing this out of all proportion - anyone who understands the dangers of Malignant Melanoma take the prognosis very seriously. Yes, I cant lie to you - it is a life threatening disease -current statistics say the it affects 1 in 50 people and 1 in 4 cases are fatal. However that equates to 3 out of 4 people living long happy lives. Statistics are just that - numbers! They are not for individual people for please dont read too much into them and scare yourself silly.
You do - I feel (others may disagree) have to tell your employer as you will require a small amount of time of work to recover from the WLE (wide local excision). Of course you cant focus on anything other than the melanoma - its one hell of a shock, but I promise you it will get easier.
The "waiting game" as we call it is the worst bit - waiting for results, waiting for treatment, waiting for the next check-ups....the wait goes on and on.
As for your daughters; teenagers are very good at picking up on atmosphere's, tension, etc and blowing things out of all proportion in their minds - much better to be totally honest and open with them. Let them talk to you about it if they want to - they will be just as shocked and scared as you are; please don't be embarrased because you showed your emotions - its very healthy and good for them to see you are scared rather than covering everything up and giving them the impression it's a taboo subject which is not to be discussed.
The most likely outcome is that you will be left with a scar, be inconvenienced by 3 monthly check-ups and be forever vigilant about you and your families moles - and fingers crossed thats what will happen. Try to relax - write down your questions and take them with you - have a look at this site for more idea's -
