Im sorry that this happened to you, but your mom sounds.. so selfish, ignorant and narcissistic…
I would cut off my contact with her, but thats just my opinion, so please get help via a therapist and talk it through, because it really seemed like your mom likes to put all the blame onto you for her mistakes.
I wish you the best luck in your life.
It may be that your mom does not like your dad and therefor unintentionally expressed these feelings towards you. In the heat and stress of the moment she may have expressed herself like that, you shouldn’t take it too personal. She of course rushed in to help you once she heard you screaming and this is her motherly instinct and love for you. Every mother loves her child in a different way, she might have her own personal issues that she reflects on you without her own noticing. I would suggest expressing your own love to her so that she gets more comfortable expressing her love to you back. Try to build a stronger relationship. One way to help her is to relieve her stress by helping her in chores or doing the groceries so she has to worry about less things. Buy her some flowers or gifts. I am sure that every mother will appreciate this. Good luck ?
So you were 12 and unable to turn off a simple gas stove ?
