I found useful to learn that it is important to have goals in order to get better. The lack of goals in the past had contributed to my depression.
Analysing the activity tracker I found that my depression is worse when I wake up and when I am presented with some problem at work. My sleep pattern is fine as usually as I go to bed and wake up at the same time.
I already posted my goals on these forums and I am working on 3 goals right now. 2 goals (meditate 10 minutes a day and visit the country side or go near the sea 1 time a week) result from pleasant activities and 1 goal (clean and arrange my home office) from the sense of achievement.
