For a short film, there is a lot here to unpack. Suicide is not an answer. No matter how forgotten or lonely you feel, you are loved. No matter how insignificant you feel, people need you. If you give-up on you, then you gave up on them.
To quote my grandpa, "Biology be damned, only love makes families." He stepped up and raised my grandma's children and never looked back. He would add, "Any thing that you do out of love, you will never regret."
Children can be very receptive and mature. Such as the case here. There is a hole in her heart dad can't fill and there is a hole in his heart she can't fill. What she can do is set out to rebuild her family.
Indie filmmakers are starving artists and entrepreneurs. For them, making movies in a true passion. They don't have the luxury of a big budget, so they have to work harder.
