I too am a carer. Taking care of my husband who has been diagnosed with MM for the past two years. He now has monthly infusions of Pamidronate and is in 100 remission. I have posted elsewhere on here that he signed up for a Trial using Thalidomide and because of the high doses involved, he has lost the use of his hands caused by the irrepairable destruction of the nerves. As you can imagine, life is pretty tough.
I would not recommend a Caregiver to use this Board to vent their fears and frustrations if the person for whom they care also has access to the same site. That would not be fair to either party. The UK has a number of sites dedicated to Carers only - perhaps a look at UK Carers (not Carers UK) might give her some idea of the type of board she may find helpful.
There are times when I could cheerfully strangle my man - and I wouldn't want him to know about it, which he would if he were able to read all my postings!!!
