That's normal! You are still very early days in this year-long recovery!I am 7 1/2 weeks out and still struggling but seeing small improvements
Something that helped me gain perspective on my recovery, was documenting my "achievements." Once a week or so, I would list of all the things -- even the little ones -- that I was able to do, along with a list of the things I was looking forward to being able to do in the future. As items moved from one list to the other, I saw real progress and it helped me stay positive. And, when I later looked back over my updates, I could see how much I had improved over time.
Why not give it a try? Now that you will be starting hydrotherapy, it might also help you home in on how much you can do without ending up on the ODIC (Over Did It Club) bench!
