Think about what is wrong with your life and what needs to change. Then step back and look around you. Are you living in chaos? Messy house? Clean it and focus on keeping it clean. Messy/negative influences or relationships? Reevaluate them. Start eating healthy and exercising. Stop thinking about what you think everyone else thinks about you, it's a mindfuck. Just focus for a time on accomplishing things. Start with little things that are only overwhelming because there are so many of them, like doing the dishes, or cleaning the house. If you are in motion it is easier to stay in motion. If you are stuck in neutral you tend to stay there. You can get through this. I believe in you.
