Hi @Suzie82 
Sorry to see you here.  All the advice the ladies have given is great.   It's wonderful you have your son to help and support you.  I wish you all the best with your treatment sending you a hug.   
If you are in Melbourne Peter Mac public hospital has a wig library you can borrow a wig from.  Social workers from hospital can help you.   Do check in with centrelink and make an appointment to chat with a staff member.
I was diagnosed with BC in March 2020.  Husband and I both lost our jobs due to covid in March and April 2020.  I had a lumpectomy.   Lump removed was 52mm and 4 nodes.  All 4 nodes were cancerous.   Then I had a mastectomy with 9 more nodes removed. Total of 9 nodes were cancerous.   I had an aggressive treatment plan.  I have had 6 months of chemo and I start radiation this week.     I found I just took one day at a time.  Rested when my body told me too.  Walked on the days I could and learnt not to beat myself up if I couldnt do any more.   Need to heal.  
Stay in touch with everyone online.    Having a safe place to chat, ask questions or even just to read others stories saved me a lot of tears and grief.   xxxx
