Been there...many many times.
Where no one was there for me, and my 5 month old baby.(21 years ago).
I mean I had NO ONE at all in my life.No family Nothing at all.
For me, I just had to make a choice (now this is just what I did) o.k.
I would have gone under otherwise,and I had a small baby.
I found a Salvation Army in my area.
What happened after that was nothing short of amazing.
Within a few months, I had so much support it was amazing!, I went to church every week...had friends-fun-and no longer despair.
They taught me that we are not alone, and that there is hope...that stayed with me for the last 21 years.
They are an amazing bunch of people.
I now never forget what they taught me, and am happy and not alone(even when I am alone).I found the real keys to not getting into that feeling I once did when as you say 'there is no one who has your back'.
You are never alone, but people just have not been taught 'how' to open that door.
Does it really work!....Oh Yes, big time.!!!!
For me that is what I had to do, or go totally under, and I would not have come through if it was not for them.
They became my friends and with some yes, even family.
I use every time I'm down what they taught me, to be happy.
This is my experience.
