2. when you feel down and you're feeling worse and worse, try going out and walking for at least 15 or 45 min, or find something to do. breathe. don't stay in one place. don't let immobility and routine drown you. if you can do something that can make you move and make memories, you should do it. depression is a brain which is being less and less active. make it work and sense stuff.
