I don't have Hodgkins, but I know the "why me" feeling, cos I've had it hit the fan with my health as well.
What I find helps, and some people will say that it's rubbish etc... but raiki (sp?) works wonders on my spine, head and has even helped my heart.
Oh, and about the losing your hair, look on the bright side, you can get a few different wigs with different colours or lengths that you can change when you want to. A mate had a bone tumour and he got 3 different wigs, and they all looked 100% real, but one was a hot pink punk rocker mohawk, one was a green and blue mullet to the small of his back and the third was a black with silver highlights about shoulder length.
