My right THR is scheduled for November 15, 2017, Yikes!!!!

I am extremely nervous about the surgery! I am 64 year old female serious Body Pump enthuiest and a jogger. My hip pain has been interfering with my physical activities and I am in need of a normal life! I live alone and am wondering how long I will need someone to stay with me after surgery to help me. I have a desk job and am hoping to be back at work in two weeks. I can have a co-worker drive me. Is that possible? I will be doing Body Pump right up to the surgery date to stay in shape. I hate to be dependent on anyone. I would love to hear others stories of the first two to three weeks after surgery. I am getting a Zimmer trabecular metal hip using a mini posterior (more like side of hip) surgery.
