Hey cute
The fact that you're coming from such a developed level of understanding for your mum does show you are a good person, so I hope you don't take any of Maritsa's unsympathetic, idiotic bullshit to heart.
Have you considered IEI? You and your relationship to your mum sounds way like mine to my mum (i'm IEI and she's LSE) - she's also called me selfish, which I think is just a differing of values and really not true in the slightest lol; IEI's can become independent and retreat into themselves for self protection. I also think we do that with LSE's because they tend to be so fucking meddling and imposing! While living with my mum I was often angry and unproductive and lazy (it was a way to defend myself against her and avoid being commanded by her) - but once I left home I became way more productive, successful and while I have a tough defense, i'm generally considered very kind and compassionate; and these values deeply motivate me (but never really grew at home because things were too painful and messed up). There's not anything wrong with you and you can't really be yourself (only you that is hurting rather than you that is positive) in a family household with your conflictor. When you get out and move away you'll begin to blossom; don't judge yourself by who you are in that relationship (it's too messy to adequately allow you to be who you are) and try to limit that relationship as much as possible; you will be SO much happier and have such a better sense of your self.
While conflictor relations are painful and damaging - I also think one of the worst things about them is how much they limit someone's character; you're not free to grow, develop and express the wholeness of yourself and all your great traits can't grow; when you get out they can
. So not helping out around the house or being lazy and independent; that's not really 'you', it's you in a bad situation. And don't take too much responsibility for your mum's own cruelty (telling you you ruined her life is just a disgusting thing to say and not right no matter what the situation) and hostility; they are not your fault, you don't deserve them and half the time what she tells you isn't true. There are going to be so many people that truly get you and love you in the years to come so please don't take this relationship with your mum too much to heart!
