Need my hand held today...

I had not brought this up before because I didn't want it to be an issue, but I find myself needing support today. My Dad, who quite frankly, means the world to me, has Waldenstroms Macroglobulinemia, a rare incurable cancer. He was diagnosed in December and has had several rounds of different types of chemo. This last round was stronger because the one before was not doing the job. He has a mass in his chest that is not going away, it may be a different cancer altogether. He had a CAT scan last Friday, getting the results today. I find myself rather nervous and scared of what my Mom is going to tell me when I call her later. He has been feeling better and his blood counts are up, so I really shouldn't worry, but that mass really has me concerned. I am trying to stay positive, but it is so hard. I don't know what I would do without my Dad. He has always represented total security to me, someone who is always there and who will help me up no matter how hard I fall. I will be totally lost if I lose him and it is very frightening.So, any good thoughts you can send my way are appreciated. I am trying to keep busy and keep the faith but it's hard to do when I am so scared.
