It took me a good 3 months before I felt secure in my j-pouch. Even longer than that to feel a sense of normal.
Have you tried going out of the house on trips to see how you do? I know for me in the early days, when I was home everything seemed worse. But when I was out & about I had longer periods between bathroom trips and the gas & pouch fullness didn't seem as bad. Sometimes it just helps to do something to get your mind off of it.
I also went back to work after 3 weeks. I didn't have much of a choice. I struggled at first with a lot of bathroom trips, but things slowly improved.
