Well just do little things that can make you happy, and that could be anything, eating, getting your favorite drink, going for a walk, drawing something. Anything okay? Make it a goal to do something for yourself daily ^^
You are amazing, you are spectacular and I'm so glad I have you as my friend. I promise you dont need to help anyone before you help yourself. Make sure you get the help you need. And if you even need help with school I'm here and I can help you. Please please dont kill yourself, I'm here for you when ever you need anything okay?
