As your are doing this, and restricting calories, are you monitoring that you are getting Adequate nutrition?
There is a difference.
I have found that if you get the nutrition down pat, get quality sleep, quality me time, and some activity that you enjoy, this is much easier.
Yes, this does mean, some times, saying, "I am going for a walk, every morning, from x time to y time.
It also requires we look at the big picture. Getting the nutrition on point, with good food, that you need to experiment with to make it taste good.
IT also requires a change in our thinking.
Changing our mind set is our biggest challenge.
Instead of "I can't, we need to get around to "I choose"
It is a process, one of self discovery. Do not give up, and be patient with your self and the process.
