I'm afraid it only ends if you choose to end it. What are you doing to heal yourself? Are you seeking counselling? Are you taking care of yourself? You are physically incapable of getting past this if you don't eat, sleep and exercise. You are emotionally incapable of getting past it if you don't fill your life with positive people and experiences. It's in your power... it's not about just waking up and miraculously feeling better. You have to fight the depression with every ounce of strength God has given you. You can do this, but the key ideas in that sentence are "you" and "do".
