@kittyroma I doubt you'll find the whole process as bad as you are envisioning it. I certainly didn't. I was terrified before my first surgery and still can't believe I found the courage to go through with it. I wasn't even scared about the second hip a month later! All the thinking about, imagining, and worrying about it is FAR, FAR worse than the actual experience. Your pain will be well controlled post op and they'll get you up in the hospital and be sure you can navigate yourself to the bathroom, kitchen, etc. before discharge.
I didn't go to rehab for either hip, as my OS feels it is unnecessary as hips do well on their own; he also told me he feels that people do better in a home setting and also that time in rehab increases your chances of picking up an infection. I went home after two days in the hospital after the first hip and three days in after the second one (blood pressure dropped after the second one). I live alone -- my daughter in law stayed with me for a couple days after the first hip and then just dropped by to help me as needed. I did just fine. I was able to get to the bathroom, kitchen, etc. and back to my recliner just fine, using a walker. After the second hip she only stayed with me one night and I did fine thereafter. Of course they came and helped me by getting groceries, hauling me back to the surgeon for post op stuff till I was cleared to drive, but on a day to day basis I managed on my own (with a walker as ordered by my OS). I did ask for someone to come and be in the house when I showered, because I was nervous about falling and had a bit of trouble getting my legs over the rim of the tub to get into my shower chair and then back out again.
You won't be laying in bed going nuts, you'll be up in a chair or recliner with legs elevated, watching lousy TV or reading and snoozing off and on, and putzing around the house. Elevation of your legs is important to keep swelling down. A home PT person came to my house several times to help me with simple exercises.
You just have to be careful to not do too much while you are recovering, but not just lay in bed. I had a hard time finding the patience to accept that it was just going to take a while and I had to take it easy. I had the posterior-lateral approach for both hips. With adequate pain control, I had no significant pain after surgery at all, until I did too much and got a spasm or something in my piriformis (small muscle in the lower back/buttock) which caused me sciatic pain. Got that settled down and I am doing great now.
You'll be so happy you did this and, believe me, it is nowhere near as bad as you think it will be. I'd do it again in a heartbeat, but I don't have another hip.

Peace and love to you.
