As it's not means tested and is for a genuine disability I'd say jolly well take it. It could come in handy for any equipment needed which could be passed on to another person when it's no longer required. The illness may get worse and earning power will go down. When my DH was terminally ill my boss said, "Whatever you're offered, take it, you've earned it." Don't feel a sense of false pride.
