I'm proud of you!! That's huge. You should give yourself a well-deserved pat on the back. Verifiable progress and it's only up from here, keep it up :)
I would lack motivation too if I grew up with a mom like that. You need to eject her talk from your head. Every day you wake up a new person and whatever had happened earlier is nothing but memories. Begin again. You're free, and life is full of opportunities.
