Should I reach out to my estranged sister

I’m in a bit of a situation. I have an estranged sister who I have not been in contact with for just under three years and I need to know, if I’m making a huge mistake in reaching out to talk to her.

Just under three years ago I was in an abusive Relationship, and my sister had been there to help. She had moved both myself and my daughter who at the time was only three months. Away from my abusive ex and into her house.

At the beginning everything was great. During the first few days of living with her I was having some problems regulating my emotions and had gone for a walk with my daughter, upon arriving home after the walk I was still feeling upset and was muttering to myself and indirectly my daughter about how life wasn’t f-ing fair.

Again my daughter was three months so she definitely didn’t understand what I was saying. But my sister had over heard and proceeded to berate me for talking to my daughter like that. I didn’t reply to my sister and headed to my room and began to close the door not needing to get into an argument with her. But she slammed the door open demanding that I don’t close the door when she’s speaking. We did begin to argue and things became physical when she shoved me backwards causing me to nearly fall on my daughter. Long story short she told me to pack my things and get out, or she’d call the police. She left me stranded in a place I didn’t know.

She also called CPS lied to them about me abusing my daughter and she also called everyone I knew who’d be willing to house me telling them not to help me. Forcing me to make the decision to return back to my abusive ex. As he was the only person who was willing to take me back in. Who then later threaten my life. But that’s another story.

Anyways I’ve been in therapy for the last two years which has been great for the most part, but apart of me wants to reach out to get some closure kind of… I want to see her in person. So the question is should I or should not reach out and try to meet her in person.
