I think family stability is one of the main core anchors behind happy people. I see such a huge difference between people who have not had family divorces, and an emotionally supportive family, vs those who don't. And I mean it's a huge difference. Not to mention children of divorce are more prone to developing eating disorders (if divorce is during a female's preteen years), drop out of highschool, have troubles socially, and develop substance abuse problems. (man did I ever prove most of those statistics correct xD)
Before reality hit family was a blanket of security around the severity of reality. It was something I could trust to always be there so much so that I never realized it was temporary, it was like an extension of myself with qualities that I lacked that allowed shy me to shamelessly be along with it. Having it made everywhere feel like home so much that I never knew home sickness. It's something that put me in the moment, excited and interactive, much of the time without feeling alone outside of my own head. The feeling of being loved due to a content atmosphere emitting from familiar sounds, faces, body language and contact, worn in to memory from the safest times of infanthood. At least the past- kinda family not the future-kind, never had that kind.
What exactly is your definition of losing faith in family? Future family or past family? If you can find one person who can see, accept and love the real you, you can create new memories, bam you have family if you can hold onto it and welcome it. Whether I've lost faith in it, my actions say yes and i'm open about the fact that I have. But I don't think I can completely, and I think we'll probably find that new extension of family one day whether we think we've lost faith or not. We're caring people with much awareness, especially emotionally, and I think we'd be more sensitive and nurturing to deeper connections.
