My baby (Independence)

I'm looking for my tri-colored female pitbull.
She had gotten out of the backyard and I have been searching for her but have had no luck.
I suffer from depression and she is my service baby that helps me get through my day.
Please if anyone has seen or found her.
Please let me know I cry everyday since she has been gone.
I just want her home as to I know it is getting cold outside and I miss having her lay next to me.
I worry about her and hoped she would return home.
I do greatly appreciate it very much for your help please and thank you.
