How to cope up depression? one way among many:

Mind is a beautiful and very good servant, but a dangerous master. Never worry about your failure and never discuss this with any, just forget and step forward, moving further is the best solution, and Movement and transformation is the rule of nature. Time is still the answer forgiveness is the best painkiller and God is the best healer. Nobody is perfect, we make mistakes, we say wrong things, we do wrong things, we fall, we get up, we learn, we grow, we move on, we live. Good decisions come from experience, but experience comes from bad decisions, this is life, never regret. Learn from mistakes and go ahead. Just you remember, Self-discipline begins with the mastery of your thoughts.  Just level up the standard of your personality. think on, find your goal, prepare some action plan, fix bad habits, focus to learn skills, think positively, be simple, maintain physical and mental health, do some meditation or yoga or exercises or workouts or go to walk on green places, fill the energy and start to work on your goal, improve it further, be a responsible person and just this much is enough for your transformation and personality development and growth towards success.
