a key thing to learn is to redirect your negative thoughts   i completely understand feeling like your body is full of sand and it taking a lot of effort even to scratch your own head but you have the power to control your thoughts with little effort   if you havent done it before it will seem stupid and take conscious effort but it become more and more natural the longer you do it  two things if you would say something to someone you care very very much about then you should be telling yourself it you wouldnt tell you best friend that they are a piece of shit and that they should kill themselves would you no so you shouldnt tell yourself that shit you are the most important person to you so you should act like it  when ever you start having a negative thought acknowledge it initially verbally to better train your brain to pay attention to what its thinking about starting to feel like youre lazy because you feel too tired hello negative thought thanks for checking in on me but i dont need you right now so goodbye  take care of yourself
