Good for you! I love it.
Because we're communicating under this thread title currently, I will add that self care not only feels good, but it gives you a sense of normalcy in a situation that can feel foreign. You feel like you have some control in taking care of yourself and it feels fulfilling early on. Within hours of my surgery, I was to dress in street clothes, no hospital gown allowed. HUH?!! I believe was my response when I was instructed to bring clothes to my surgery site, to put on before I left the post op recovery room to head to my private room for the overnight. Naturally the clothes I brought were lightweight, loose and comfy, like pajama comfy...and a bra was a "no go" for me, flat out refused that one.

Nurse laughed and said she understood and didn't blame me.
The theory is that being in a hospital gown can make you feel like a patient. I thought I was a patient?!!

They just rendered me unconscious, sliced into my flesh and sawed my bone, doesn't that qualify me as a patient? Lol.
I do remember that first shower, which although quick, felt like one of the best ever. Aaah...to have clean hair again too. Wonderful! I also began blowdrying or styling my hair early on as well as applying "minimal" make-up after catching my bedhead in the mirror each time I'd use the bathroom.

Depressing! This may not be for everyone, but it truly made me feel better.
Still very early days for you, but I believe you'll reach this point soon enough and it does do a lot for our mental health as it provides comfort, familiarity and it feels like a big accomplishment also.
