Mastectomy. Now what?

Hi all,

It feels odd expressing how I’m feeling on here. I was diagnosed with Stage 2 BC, Her2 + back in November 2023. I was breastfeeding my 16 month old son and it hadn’t been long since I’d been back from maternity leave. I was told to stop breastfeeding straight away. I went to get the lump checked on a whim; never did I think it would acrisply be cancerous. 
I’ve completed my 6 rounds of chemo, ended up being admitted in hospital on 3 separate occasions, had a lumpectomy last month and then had a mastectomy on Monday (03/06/24). 
It took me a long time accepting my diagnosis. Chemo was hard. I hated it. Not to mention the side effects and then the hot flushes from the early menopause. I never spoke to anyone, except my husband but it was too much for him. I feel like no one will ever understand or can understand how I’m feeling. 
Now I’m feeling completely broken after the mastectomy. I’m young. I never expected it to come to this. I feel sad that everyone gets to move on with their lives, but I have lost a part of me. I’m happy for people getting on with their lives, but I feel I’m stuck in limbo. 

I have an app with the oncology doctor on Friday. 
I just wanted to know from others what to expect from this appointment. I always attend these appointments never knowing what to expect; they literally last 2 minutes and I leave feeling stupid because I didn’t have much to say or discuss. 

Sorry I know it’s information overload on here, but I felt I needed to give some context first. 
Also I have been referred for some counselling. I finally mustered up the courage to speak to my Breastcare nurse about this.
