One thing you have to do is "stop feeling sorry for yourself". Bad things happen and bad situations may occur. Even though it not your fault, you have to accept its your responsiblity. So once you got those things in your head, you have to learn to fo stuff one at a time. Be patient and develop good habits. Starting small by getting up early, cleaning house for atleast 20 min a day, making your bed.... not checking social media when you just woke up.... slowly they will be part of your daily habits ....
