When you are frustrated and depressed the first thing you should do is find out what can change your mood. Some things are inevitable and you can't change them if they are coming at you. In such case it is better to have something that can please your mind. It could be as simple as listening to music, taking photos or even writing something. The thing is that if you keep on doing something that pleases your mind. And then move onto something difficult. That approach always changes your mood and also the results. You can't change outcome unless you change the approach that caused the problem. You have to approach this from different angle. Make 2021 different by changing the ways you think that caused the problem. :)
