So sorry to see you join 'the club', @ninica - but you'll get a wealth of support and tips here, from those who've gone before you.
I was lucky & dodged the chemo bullet & went straight to Rads & Tabs - but my husband had one node affected (out of 50 tested) with his stomach cancer - and altho he didn't 'want to' - he did decide to go with chemo, as it is to mop up those 'randoms' that may have snuck thru the net. :( Both your opinions have suggested chemo - not everyone gets really crook - quite a few here have continued working thru their treatments - if you go down that road, fingers crossed, it may be you.
There is a 'Young Women' group here that you may like to join, to discuss issues with in private (only group members can see the posts.) . You can raise any issue you like with them. Clicking on it will show BCNA, @InkPetal and @jane84 as contacts for joining ...
