Pretty much take it one day at a time. Sounds silly and cliché, but, it helps when everything is a tuggle yo get done. Even the smallest things. But, this is how you do it. Slowly. Start one thing you are struggling with and make it a daily routine to fix or do it. Once it becomes habit, move on to the next and the next until you are functional enough to take the next step of healing yourself. But first, you have to take care of yourself. One step at a time.
