I don't know what to do...

I feel so emotional right now. I want to break down and cry. I don't want her to be mad at me forever. I'm scared if she is going to hug me and I might flinch. There is so much that is going on in my mind. Right now.

Well.. the whole story started when I was talking to her children and they wanted to ride in the car with me. And I didn't think anything of it. But she looked mad when I said her children wanted to ride with me. Im used to watching kids. I did that for over 4 years. And I know she must be over protective and worried for her childrens safety. And she told me if I don't stop. She will yell at me. I was trying to help. I figured she could use a break from watching them all the time. I didn't know it would bother her. I don't want to be yelled at. I had enough of that from my sister.

Edit...

My sister isn't a bad person she is a person who built her walls up so much. I figured that out a while ago.
