Hello @Jackie,
So sorry about your Mum but I am sure that you will always be glad that you are able to be there for her in this situation. It must be difficult not to think and worry about your own situation as you help your Mum. But, as you say the lung cancer is most probably from the heavy smoking. So many of us have radiation to the chest area but most of us do not, thank goodness, develop lung cancer. I would imagine that the risk would be higher for a smoker but a doctor might be able to put your mind at rest about this.
Fear of recurrence or even another type of cancer or serious health issue is something that most of us experience. Different situations will bring that fear back to the surface, like with your Mum. It helps me to take control of what I can in my life to help me feel as though I am actively doing something to lessen the chance of this happening.
As I said, none of us know what the future holds but it helps me to make the best of everyday right now. It has given me the energy to make changes to our lives.
Is it possible for you to do something nice that you enjoy on a daily basis while you are with your Mum? It is very important to look after yourself at this stressful time. Keep in touch on here. We are here anytime you need to chat. As you say it helps to get support from others who really understand. Take care. Deanne xxx
