I'm speechless too, and very touched, thank you Sheila for these words, this gives a good image of how I feel very often too...
Cut off from the rest of the world because I didn't have parents who supported me, and told me I was a great person no matter what.
In my case too, all the social skills I needed to be a self confidant person were in my left arm. They weren't stimulated, or developed.
I never felt truely loved. So I had to learn to love myself, and to look after myself. By telling people they're hurting or mistreating me.
My left arm is still very weak, but I'm using it, to make it stronger.
