Should I talk to my mom again after she called the cops on me for nothing.?

No. Dysfunctional people rarely change. If your mother is this way and you know it, why in the hell would you want to live with her to begin with? I would make every effort to avoid her toxic behavior. You gave prime examples of someone that is not going to be a healthy person to live with. She might be your mother, but you are not obligated to live with her. That said, if you choose to live there then you lose the right to complain, period. If you keep living in a place that isn't healthy and expect things to go well, that's on you. Your an adult, and fully capable at age 41 of being smart enough to make choices that don't put you in jeopardy of being mentally, physically or emotionally abused. Get the f*** out for god sakes or accept what ever sh*t gets thrown your way.

i would rnove out, i wouldnt want to live with sorneone that did that to rne

The real victim here is the foster child. You need to think about what is in this child's best interest, and it doesn't sound like living with your mother is it. if CPS wants you to be the foster mother, then step up and do it. You need to talk to your apt. mgr. about breaking the lease under the conditions you've laid out. You might be penalized if you leave before the lease is up. It would be better if your mother left, if your name is also on the lease. If she leaves, try to find a roommate who is okay with the foster child and will be compatible. That way, you can still afford to keep the apt.

She needs to be committed, that is why the Social Worker wants you for the kids Foster.

Move Out, don't come back until the will is read.
