You have no controll of the future nor the past, dwelling on it isn’t going to change anything but make the present insufferable, stay focused on the now and what u can do not what u can’t do or what u wont be able to do later, I think with ms having so many possibilities it makes it impossible for us to stay in the moment because we have so many worries and no one to tell us it will be okay. Well… it will be okay, stay in the moment!!!!
