Women who had chemotherapy less likely to be employed 4 years later

[Lnmum]

I have just had 7/12 Taxol/Herceptin treatments. I have observed a significant decline in my cognitive skills since my last treatment. It terrifies me that I won't regain my processing skills/STM.
I was offered a prn speech therapy position, but now I am concerned that I won't be able to perform that position effectively.

I found out I tested positive for BRCA2 two weeks ago. I am questioning my entire chemo regimen. I'm having bilateral mastectomies as a result of the positive BRCA2. I'm also having a complete hysterectomy. I was stage 1c,IDC 1.3cc ER+ 98%/PR+ 2%/HER+++. Body scan revealed a lung nodule. The doctor said no worries (but I am). Bilateral mammograms after partial mastectomy were clear. No radiation recommended by breast surgeon. He says no need since we are no longer interested in breast conservation.

I'm reaching out for advice and hopefully some encouragement. I know there are others on this board who have been in my shoes (or some that look awfully similar) Thanks!
