It's going to get better, and I used to feel the same way as you did once. I even wrote my suicide note. But then I realized. There is always something to look foward to. Is for the people you will meet someday and care for you. Even to the people you know care. We can't ever go back a day, we don't live forever, so make the most of today. And look foward tomorrow. Everybody has bad days, but that's okay. Just know, one day it will all change. It may take a long time, but I know it will get better.
