Mastectomy next week

Having a mastectomy next week and I’m very upset.  I had wanted a reconstruction at the same time but the surgeon says that that isn’t possible for various reasons - partly as the operation needs bringing forwards as the cancer is growing and partly as I will need extensive radiotherapy and he thinks that the result of a reconstruction may not be very good due to that. Due to other medical issues, including extensive abdominal surgery and back problems and having chronic health conditions , a tissue reconstruction may not be possible/advisable.  

i feel that I will never be able to go back to my normal life and activities with just one breast as I have found it impossible to get a comfortable mastectomy bra as they tend to have big cups and come up higher at the sides and thus dig in.  None of those in M&S fit and most mastectomy bras are in the same few styles.  I tend to wear scoop necked T -shirts snd like smooth, seam free and minimal bras.   I have ordered some soft crop top style bras from Amazon for the first few days post surgery but the support isn’t as good as for a proper bra and all that fabric is a bit hot and sweaty.  I am also aware of Asda’s range but they are out of anything that I like in my size and I’m not sure that lace is a good idea and prefer smooth bras anyway.  
most upsetting of all is that I am a swimmer and cannot find a mastectomy swimming costume suitable for someone fairly tall (needs to be long enough in the body) and with bigger cups (E plus).  I was a G cup before cancer weight loss and expect to put on some of that weight again.   I have narrow hips and shoulders so if I go up a size, end up with clothing hanging off me/falling down.  I’ve always worn Adidas or Speedo swimming costumes as these fit well and are comfortable but  these cannot be adapted.  I have a bikini with F cup but it comes too low to be able to sew in a prosthesis pocket.  I hate costumes with skirts and things like that  - I wear proper sports brands.  

I am disabled and have arthritis and mobility problems and swimming is the only exercise I could do and a large part of my social life.  I have been in M&S (swimming costumes are short in the body and the prosthesis pockets are tiny) and this seems to be the case if I simply look for my dress size.  I have looked at Nicola Jane, Amooena and  other specialist sites and most costumes only fit up to a c cup.  There is the odd one that goes up to a D.  
while I still hope that I may be able to get some sort of reconstruction or reduction of the other breast at some stage, this could be a considerable time down the line.  
Has anybody found a sportswear brand that does mastectomy costumes in E+ cup, preferably one that does not come up high to dig in under the arms?

Have you had a look at Nicola janes range? Jill I think it’s Nicola Jane a lot of women order from isn’t it? I’ve not used personally but might help sallybadbunny. Can you please confirm it’s Nicola Jane that’s another place they could try finding something suitable thanks :two_hearts: :two_hearts: :sparkles: :sparkles: Shi xx
