It must be very difficult for people like yourself who have to take time off work and travel so far for treatment. It is hard enough dealing with a BC diagnosis without these additional issues. Leaving your home and presumably your personal support network of friends and family and your normal routine of work and living must be very hard. So don't feel that you should just be able to pull yourself together and cope with all this.
In saying that though you do deserve to feel as good as possible so getting assistance at this time is a really good idea. The cancer council is brilliant for counseling and also for financial assistance info. You may be eligible for assistance with travel and living away from home while undergoing your radio treatment.
I think it helps to let others help out and recognize that this is a tough time for you. Acknowledge to yourself that you are doing very well considering. Being diagnosed with BC is not easy and letting others give you some support (and realizing that you deserve this and would probably be the first to help someone else in the same situation) will make it easier for you. Keep in contact with the ladies on here, especially while you are more isolated during treatment. It really does help. Wishing you well with radiotherapy. Take care. Deanne xxx
