I'm sorry for all the wrongs, hurts and abuses that were done to a sweet little angel.

(I think of all little children and domestic pets as "angels")
You are right-- you aren't theirs. No living thing can be owned-- each being is just visiting and learning-- no one is owned.(IMO)
I think of adults being/behaving around children as important tests-- do the adults pass or fail........
I know some that failed miserably around me.....
I believe this "grade" will hang over their heads for eternity--
in that, I have a bit of solace.
I hope you know that the adult/s that abused you failed -- NOT you.
You are unique, a treasure, a gift.
good going-- giving a voice to that which needs to get out.
we'll listen as often as possible!
in my heart,
fins
