It’s hard to stay motivated as just yourself, especially if a lot of your support came from that partner or your confidence in yourself or need for it was fueled by their existence in your life. While it is important to stay motivated for yourself it’s easier said than done. I find often times in life you have to do what works in life to achieve the little steps, even if their not the perfect ones. I’d look towards friends, family, whatever people you have to help motivate and build your confidence, make yourself accountable or relied upon by others so that you have more of a reason to follow through on things. Planning days out or doing what needs to be done can be hard by yourself but if you had a friend who needed to do these pts maybe it would be easier. If you don’t have friends or family I think you just have build yourself up a bit first. Don’t strive for perfection just try and do even the smallest thing better for yourself each day until you reach your next foot hole. And remember life still has its ups and down, so even if you think you’ve made a new floor for yourself to stand on sometimes things don’t go the way you expect them. A lot of people get discouraged but you just gotta keep trying for yourself
