Everyone keeps telling me it’s because my mother is losing control of me but I am still not too sure?

My mother is control freak, whether she likes it or not. A few months ago my husband (who has never absolutely loved my mom) and I decided we are going to move to the east coast. It’s a huge move and no one in either of our families has ever done anything like this so this is new territory for everyone. Everyone seems to be happy for us including my mom but yesterday she lashed out at me regarding some furniture that we took that my parents said that we could have for our first home together. She told me that because my in laws are coming over to help us move our stuff that she and my dad do not have to come to help (which I told her I never expected them to feel like they needed to). She then hangs up on me and calls me about 10 minutes later to tell me that they will be over in about an hour to come get the furniture from their house so they do not have to come to help us move, even though at this point my dad told me that he would come regardless of what she said. She then calls me again and tells me that they won’t be coming over today and will just come tomorrow because she wants to help us and this sent me over the edge. It’s exhausting and my husband says it’s because she is losing control over me and doesn’t know what to do but I cannot help but think that there is some mental health issues happening that up until recently I did not see. What do you think?
