Tree Branch Fell Taking Out Neighbors Power

A big tree branch just fell from my yard taking out my neighbor's power. They are screaming at me. We have not had a good relationship. I (51F) went inside. I didn't feel safe with several grown adults yelling at me. I have no one who can help me at home. I usually do but my family member has cancer and if very ill. I know I need to call a tree service but it is Sunday. If the neighbors weren't screaming at me I would talk to them about trying to get a tree service ASAP. I am afraid to go outside. I know they are going to say I just left them to deal with it but I'm totally freaked out.
