The way to expand from individual to universal consciousness is to share others's sorrow and joy. As you grow, your consciousness should also grow. When you expand in Knowledge with time, then depression is not possible. Your inner most source is joy.
This is what knowledge does, it cleanses our mind from all this; cravings, aversions, sorrows and regrets are taken away and you feel alive and fresh again.
If you act towards others with an intention to gain something from them, then you will have to face sorrow and pain.
You should love your friends and relatives but do not demand anything from them, or get attached to them. You should serve them in whatever way possible. When you set out with a sincere intention to serve then you will never face any misery or sorrow.
Whether you experience happiness or sorrow in life, treat both as equal, because happiness bring expansion and sorrow brings depth, and both make you stronger. And the way to go beyond both of these is meditation.
