I have read some of OP posts and its clear she had a ****ty home life left home and had a baby quite young, can't drive and has no family and friends really, her confidence must be low at times. It's clear she loves her kids and is doing the best that she can, sure encourage her to get her licence but that's not going to happen over night, what she really needs is a large dose of confidence in herself and things will grow from that.
Seems for some people around here putting down an easy target makes them feel better about themselves. A bit of kindness goes along way.
Hugs OP if I met you in real life I would give you a hug.
