A decade ago, I would have thought I could answer your question OP, but over the last few years, I've realised that my mum is actually quite toxic. Other mothers mentioned on here seem to fall into either the good or bad categories but mine seems to be more in the grey area.
Her intentions - very good, she definitely wanted to be a good parent, loved me, went out of her way to give me a good life. She's kind by nature and definitely wants the best for me. But her idea of what's best is often different from mine, which is fine and normal, but her lack of boundaries is not, and the pressure she will put on me to do what she wants can be intense and has caused me extreme stress at times.
She's also very impulsive and single-minded, which has led to some incredibly poor decisions, many of which have impacted me massively, sometimes catastrophically.
My sister is disabled and my mum has pretty much dedicated her life to her, which is admirable. But it has complicated our relationship because my mum seems to resent things I have that my sister can't have...it's obviously more complex than that but I'd be typing all night.
Essentially, she is on the surface a very nice lady and a loving, supportive mum. But her behaviour is bonkers at times. I don't feel she's my best friend or someone I can really rely on. I feel very stressed out in her company.
I still have a pull to be around her though...maybe as I'm often vying for her approval as she's incredibly hypercritical of me. And when she's gone one day...well, I will struggle with the loss, I can't imagine it really.
Sometimes, mothers are complicated!
