Was I too harsh with my mom?

Okay, long story, sorry! So I'm pregnant, and my mom painted a dresser she had for me to use in the nursery. Right now my husband and I have two full beds in our bedroom because I just can't sleep with him in a smaller bed, so we ordered a huge king size bed so we can sleep in one bed again. Currently our bedroom has absolutely no space other than for our two beds. The other bedroom (the nursery), is also filled with some stuff and is quite a small room with a closet kinda jutting out. We need the entire nursery to be able to air out our king mattress that came in a box for 48 hours. The mattress is at my father's house right now because a shipping mixup. We can't get it without a truck which we can't do until Saturday. So essentially we need the nursery free of clutter so we can air out the mattress Saturday and let it expand for two days. I hope this makes sense. We still gotta be able to sleep so we can't move our beds out of the bedroom until the mattress is ready and done airing out. So there will be no room in either rooms for anything for two days. The rest of the house is small and jam packed as well. My mother and I were supposed to go shopping and have a nice day tomorrow morning. She emailed me saying she was bringing over the dresser. I was caught off guard and told her we really don't have a place to put it because we need the room to air out the new mattress. She got kinda shitty with me and then called me up with an attitude freaking out saying the whole point of the trip to go shopping was so that she could drop off the dresser. I thought the point was to just have a nice day. She made me feel really guilty for asking to bring the dresser on a later day so we aren't having to keep a dresser in the middle of our kitchen for two days. She told me on the phone she couldn't even talk to me she was so upset. I was so hurt that she got so nasty with me on the phone that I just cried. These were the emails we exchanged. She called me yelling and being rude after she sent the "whatever" email and the one after that. I got a little fed up with her blaming me for everything and felt the need to state my feelings and stand my ground. Was I too harsh at the end? She manipulated me a lot when I was younger and I get tired of her making me feel like crap. Did I do the right thing? My husband says the last message wasn't taking the high road and stopping to her level. I think with all the things she's put me through, it was called for.

(Just for context my mother only lives near me during the summer, then she goes back down south over 1000 miles away. She's 51, I'm 23, yes we email because it's easier for her)
