Acceptance - Accept self and others (with or without depression) without asking for a change. This is the first step in healing. You can't change something if you resist it as the resistance keeps the energy flowing in that same direction that you wish to alter. Haven't you fought enough already? Let's change the dynamics and accept it, to release it.
Compassion - Choose compassion. Choose the wholeness of being instead of viewing yourself as someone who needs 'fixing'.
Routine - Fix a morning routine to take time to feel gratitude, meditate, read a few pages of a book while sipping tea, exercise, write a journal, sleep for 7-8 hours daily and take a cold shower.
Seek support - Ask for help and seek professional support from a therapist in case the situation is extreme despite the self-help, positive lifestyles changes and support from family and friends. There's no shame in seeking help to be healthy!
