my grandad who is well into his 80's now went into rehab for 3 weeks after a succession of strokes before he was transfered to my step mothers house, they said he would not make it past xmas, he is still alive and bit.ching now 4 years later, so dont be so hard on yourself

also i would put of if you can the visit on saturday, leave it til monday to give your legs a chance to heal or at least to stop hurting
