Rare cancer

Hello all , new to all this so am sorry if title is wrong!! 

The last 18mths ive been going through a rare cancer diagnosis doing it alone . I have malignant melanoma vulva cancer , and was wondering if any other females have or going through the same ? 

Currently just started using Imiquimod cream and as a whole wondering how bad it can get with pain and general skin breakfown. 

Had a big meltdown and am only week one into 6week course

In a lot of discomfort even doing basic things . . 

Any advice on how to cope with being able to continue to work , coping with pain and mentally staying strong? 

Thank you
