My mother gave me away and now she acts like she cares?

My mother gave me and my younger brother up for adoption at 4 years old. And didn’t keep contact with us for years, now that I’m older she tries to be in my life but I can’t shake the feeling that she doesn’t actually care for me. When she’s angry she doesn’t think straight and is so cruel. Should I just leave her alone?
