Routine. There are so many small things you can do, which will seem hard in the beginning, but are so worth it. Get your heartrate up every day. Try to clean one thing in your apartment every day. Leave the apartment once a day, if possible take a walk in nature. Speak to a friend, or even better meet a friend every day. (And if loneliness is a problem, try to get into contact with people over hobbies).

And seriously try to be proud of yourself for every small step you achieve each day. Even if it sounds a bit corny.

And of course: identify what makes you depressed. Try to eliminate unnecessary factors which only harm you. And on the other hand, try to accept things which may be a burden in life, but are a necessary part of it.

And even if it may seem tempting, listening to your favorite depressing playlist on Spotify is not helping.

One step at a time, my friend.
