Job/life/

Hello 
I am a shy person, and I'm learning to set boundaries, my beauty salon wouldnt help me because i went to another salon, and i pay on time. So i left.
My exboyfriend who use to beat me, was put in Jail because he shot the maid and he was to return, he made his bodyguard call me, even his daughter. He has being married more than 2 times. 
I dont know why people can be so mean. 
I dont have friends in my job, i gained 2 pounds from my beautiful body.
I think i am improving.
What do you think? Please
