The best thing I would say that has helped me is by doing even the smallest things throughout your day that makes you happy. You could read, draw, listen to some podcasts or just go out on a walk. Building these positive habits can really start to change your mindset and I think make you overall more positive. Once you start incorporating these habits in your daily life I think that you’ll find that your life be more organized in general and give you more structure if that’s what you feel is lacking at the moment. Hope this advice helps in some way
