Ros is a founder member of the Let’s Do It For ME team and has done a lot of fundraising for IiME despite being severely ill.  She is currently still rather wobbly from a relapse at Christmas.

As usual, for May ME Awareness week she has come up with a suggestion she would like to do –

Guess the Weight of my Guinea Pig!

Guinea pigs have been a great source of comfort and companionship to Ros throughout her illness. Currently she cuddles her guinea pig, Herbert, while she is having her final medicines in the evening and he stays overnight in her room, as he has done for many years. It is well known that a number of severely affected youngsters enjoy similar 'furrytherapy'.
