Changing any behaviour can be challenging whether you are trying to find exercise you actually enjoy, get more sleep, spend more time with your kids, read more, increase the variety in your diet and the list goes on!
Advice? Make changes that feel good to YOU and it will get easier. Make changes out of punishment or for reasons other than your own and those behaviours aren't likely to stick.
Focus on what's gone well in the past and what hasn't and learn from that. Remember that every day is a new one and a chance to try again. Do the best you can TODAY. It is enough
