I’m sorry to read that you are having a pretty tough time at the moment. I’m sure the users of this site will be along to support you soon.
In the meantime you may find it useful to have a look at the BCC publication on radiotherapy, it looks at what radiotherapy is, when it is given for primary breast cancer and its possible side effects. If you would like to order a copy or read this on line just use this link:-
Also if you would like to talk things through do give the helpline a call on 0808 800 6000. The staff there are able to offer emotional support as well as practical information. The lines are open Monday to Friday 9.00 to 5.00 and Saturday 10.00 to 2.00.
Best wishes Sam, BCC Facilitator
