If you are feeling down, the most important thing to remember is that it is not permanent. You are not alone. Even if you feel like everything is a blur right now, whatever it is, it will pass. Also, feeling down is normal and everybody goes through it. It’s what makes us appreciate the good times. Cry if you must, or take a nap. You deserve a break, so do not feel guilty for feeling what you are feeling right now. Watch comedy or try to divert your attention by doing something that you really love. Maybe draw. Most of the time it helps.
Talk to somebody and do not be afraid to ask for help if you cannot seem to turn it around. Again, you are not alone. You are loved and people care for you, even if it might be hard to see that right now. Reach out to your family and friends, or ME! You are strong. Hang in there.
