My mum is saying concerning things after we argued

So some context, me (15M) and my mum (39F) live alone in a flat in England.

Last night we had a huge argument, or more rather she blew up after we had a disagreement. We were just talking about football and she said that a team won a final, who I told her didn't, she said she meant something different and I was just explaining to her what final meant in sports terms. She started getting defensive and ended up blowing up and shouting at me for hour going on a rant about how I'm gaslighting her, that I lie to her and how I don't respect her ever. She said things like I steal from her and even spit in her water which are thought that'd never crossed my mind. She finished a few hours later and told me to go sleep.

Today is the morning after, she woke me up with some oranges and hot chocolate and was really lovely but I was still hurt from yesterday, she still didn't say sorry and instead jokingly claim it was a dream. I (and this is where I think I messed up) said I think for this to not happen again you need to briefly tell me what exactly I did to upset you initially so I can apologise and not do it in future, I specified briefly because she tends to ramble as stated above. At first it was OK and she was saying she doesn't like it when I argue with her over little things but again it spiralled into her saying how I stress her and lie ect... I tried to stop her before she carried on to say that it's OK I get the point but then she snapped. She started screaming and hitting herself and fell over crying. She ran out the room and came back still crying and sat down. She then started saying things like she has no life left, and that she hopes she has a heart attack so she can stop stressing me, tbh she said a lot of things and still is, she also keeps randomly hitting herself in between her talking about how much I hate her and how much she hurts and wants to leave or die.

Since this she's apologised and said I should know she'd never do that and she's sorry for calling me names, should I be concerned or were her comments just out of anger due to something I said, I'm happy to answer any further questions.

TL;DR I disagreed with my mum and she blew up, I tried to get to the bottom of the issue but she blew up further and threatened to leave, and now she's calm again, should I be worried?

Thanks in advance.
