I wouldn't advise for that to be honest. Maybe OP is mistaken her opinion of what's going on, regardless , there's better and more harmonic ways to deal with this.
You wouldn't want something bad to happen to your family , wouldn't you? Sometimes our family might say stuff or do stuff but the cases where they truly are psychopath and want to harm their own children are very small , I wouldn't send back bad energy towards my family , regardless of how stupid they can be sometimes.
Well it could be, a more harmonious attempt could end up happening, that could be the best thing
But in that case she wouldn't be generating any negative energy here just by sending it to the person who sent it to her, OP could clean her aura, do meditations to improve her relationship with her mother, that could be the right option.
But in my case my opinion is much more different, in case she ends up needing her mother financially or something else important, yes I think you're right and that could be the best option
But in my case although this is the most lucid option I find it at the same time an abomination, everyone who commits an action like this or similar should suffer for what they themselves are creating, because if the most harminic option happens it would be by the result of the OP but what if she had no way to defend herself? Do you really think her mother would do the same for the OP? I don't think so
Following my thoughts and opinions, and going two ways we have
1. If you meet a negative or even nefarious person and they do repulsive things to you, try to kill you and make you feel worse, in that case, if you have the means to defend yourself and succeed, and you decide to help them spiritually because it could be more harmonious for whatever reason, everyone would have a happy ending, the person would apologize and grow up.
That seems really sensible, since you have the knowledge of how the soul works, the mistakes that this person could have made and so on, and you would be going for the best option.
But that would be you, with the knowledge that Satan gave you.
But what if it's the second case?
2. Everything happens as above but you didn't have this knowledge and you didn't even meet Satan, this nefarious person does whatever he wants to you, kills you and you could have suffered a terrible fate and your soul is now gone because it's too weak to be reincarnated because of this person, then another comes along and the same thing happens but he's much stronger and so he takes the sensible option and they both have a happy ending.
Of course this can't apply to the OP's mother and everything has its level, in this case I may be going to an extreme level.
In this case, the OP could really try something more harmonious, especially if she's going to have to live with her mother, that could be the best option, in which case I think you're right, but at the same time I disagree, because the OP wouldn't be creating negative energy, just making those who created her suffer instead of her.
In the end, in any case, the best option would be for the OP itself to decide how it's going to be.
If I'm going to give my final opinion on all this, then yes, I think that trying something more harmonious might actually be the case and also something that would benefit her.
