So much pain!

As you know I was diagnosed with spd couple weeks ago and since everything's gone down hill. The pain has progressed rapidly, I have a support belt, crutches and co codamol but I'm crying everyday with the slightest movement. How am I suppose to use crutches on a school run with 2 children? It's getting me down so much and still another 14 weeks to go till my c section. Anyone have any other ideas of pain relief I'm so stuck and so sad ??
