Counting down the days..

Hi all. I have been following this site for quite some time. I am a 34 year old mother of 5 year old twins and was born with hip dysplasia. I have advanced
osteoarthritis & no more cartilage left in my left hip..I developed a love for running around 30 and miss it so much! I’ve always had pain and knew i was pushing when i would run, but the rush of feeling so alive is what kept me at it. My THR surgery is scheduled for April 3rd at HSS..I’m pretty nervous & hope this is not something i say “what did I get myself into?”, but desperatley want to be someone who says “why did i wait so long?!”…I need to get out of this rut that’s not quite living to me. The pain and inability to do pretty much everything has made me someone I don’t even like. I am trying to get myself into the right mind set for the road ahead and have my THR Tough shirt already!;) Any words of advice?
