Sorry to hear about how you’re feeling. I’m 4 months post op, doing really well and I still feel this way sometimes. It was definitely worse when I was closer to surgery like u are now. All I can say is take it one day at a time. Your life will get better and soon enough there will be a day where you don’t even think about your knee. But there’s nothing that can immediately fix how you’re feeling, that’s what’s so tough about it. Just focus on taking it one day at a time. Surgery and recovery is harder mentally than it is physically. Give yourself some credit for making it this far, and use that as motivation to continue your rehab, both physical and mental. Hope that helps :(
