Have you tried this?
I put a sewing pin on a bag of water early this morning. This is what it looks like!
After taking pictures of it. I removed all the pin I put and all the water leaked as ussual.
I had so much fun of watching it.
I know it sounds so ridiculous and childish but I don't care because no matter how it look like the thing is, I felt happiness.
Try and have some fun. The world is full of misery, sometimes viewing things like cupcakes and rainbows make it easier for us to deal with our miserable world.
I have not tried this. And I'm so sorry to hear you say the world is miserable. In some ways it is. But in some ways it isn't. Remember that there are ways in which the world is still wonderful. They are all around, just keep your eyes open for them.
