@Happy girl
Just read your posts. So glad you found us hippies. We are a crazy bunch but a group that has simply blessed me.
Shower issues. I was like you unsure of myself getting in and out of shower. I did not have a seat. My husband put down a mat and 2 handles on the wall of shower. One right as I entered the shower. I used that handle the most and gave me confidence along with the mat. My PT also had me practice getting in and out of shower. I had posterior so my husband had to wrap me with Saran Wrap from the waist down to thighs to prevent my incision from getting wet. Now I will say, and you can read about it on my thread, that my husband did not stay close by when I took a shower as I asked him to. He wanted me to gain confidence but at the time I was very ticked.
I had ups and downs as well just like everyone else. When I came home from surgery, my leg was fine. But a few days later my leg started to swell along with my knee. It took about 2 1/2 -3 months for the swelling to subside.
It takes awhile to gain confidence. I'm 4 months out now and still am abit cautious. Yesterday was the first day I could actually tie my shoe and trim toe nails!! I haven't been able to do that for about a year. That was a big confidence booster. I walk 3 miles a few times a wk and I was able to finally ride 8 miles on my bike the other day. (My husband and I are bike enthusiasts).

No, I won't be doing tricks on my bike nor 30 miles a few times a wk this summer. But I am at peace about that. Considering where I was last year at this time, it truly is a miracle and a blessing.
So good luck and hang in there. It does get better. I will check in on you again!!
