How can I feel grateful to my parents when I feel they didn't love me enough?
Remember who cared for you
You were once a helpless infant, and someone cared enough to bring you to where you stand today. If you have no love for them, at least have gratitude, because gratitude keeps you sensitive to the contributions that come into your life.
If you have no love for them, at least have gratitude. If you lose your gratitude, in some way you have forsaken your humanity.
