Be thankful for the life you have.
There will be rough spots. You will feel bad every now and then. There will be times when you can't see the end of any suffering. But you just gotta look at the light. There's one at the end of every tunnel. No matter how long that tunnel is. Once you step into the light, you'll forget all your worries. You'll realize that it was all just making you stronger, and that you can now fully appreciate all this bright, colorful, and gorgeous beauty. So focus on the light and keep moving.
