AliCatS, I am sorry to hear about your predicament. Your story sounds very tragic.
There are many forms of abuse. The article you linked is not really the reason you are suffering. The article discusses things a parent can do to their child, but does not discuss the underlying causes. Your mom sounds like an unpleasant person. I am sorry about saying that. You love her, and care for her, so it must have been hard coming to this realization.
You probably think you are going crazy, and can't understand why you are going through what you are. The reasons won't be apparent, and you feel something is off. If you feel something like that, you are probably being gas-lighted. If you are, you cannot control it. It is what it is. The best way to deal with that kind of behaviour is to disengage. You can read up more around the internet on this type of abuse to assess your situation a bit more accurately.
You however need to keep your confidence and recognize your mother is trying to break you down, for your sake and that of your daughter's. Your financial predicament is stopping you from moving out. You need to provide for your daughter first and foremost, so you are going to have to shield your daughter and try keep your cool. Don't blow up, don't fight or don't be critical with your mother. You can try talk to your mother about it, but I suspect it will only temporarily halt the issues. If you do approach her, be sure to stay calm and to the point. If your mom is mentally abusing you, you will feed into her problem. She is craving a reaction. She will use anything to trigger you. The best way to prepare for it is to expect her to come at you. Your mom may not even be doing it intentionally, but I have come across personalities that are naturally abusive or exploitative.
You need to make a plan to get out of your environment as you cannot sustain this long term. Sustaining this mentally for a long period of time will not be possible as you will be constantly fighting off depression.
To get you through this period, seek out friends who you can talk to you about this. Or even go to counselling. It sounds extreme, but if your mother is mentally abusing you, you need someone rational to talk things through. I am not religious, but if you are, a lot of churches have counselling or social programs you could get involved in.
Strength to you.
