The smallest things
In a good period it is important to enjoy as much as you can. You should do as many things that bring you joy. A problem is that a small thing can ruin the good mindset. When a thing, either small or big, happens it may cayse your entire line of happy thoughts to come crashing down into the ground. This does not have to be a thing that relates to your depression or life in any way, but it is still enough. When such a thing occures it is difficult to retrieve the positive emotions, but it is not impossible. Let your emotions come to light. Do not be afraid to tear up or do what you need to do. When you have let your feelings show you can try to do something you usually like to do. It might not seem like it will give you joy, but try! It might be wise to talk to someone. Either a trained professional, a friend or family. Talk to someone you feel free to open up to. This was just a small tip from me. I try following this tip myself, but it is not easy.
