Im struggling

I've had to process one of the hardest things of my life, labour and being a new mum. On top of that , I have been mentally scarred and traumatised for the way my mum has treated me. She has shown narcissist behaviour and all she did was bad mouth me online, make up lies that she wasn't included or invited to see him and hasn't once asked me how I am coping following labour. She's spent the time posting her grandsons pictures and how she loves him for all to see. But has met him twice on short visits, told me how to dress him and left. It's too much to process and things growing up are now making sense. She lacked empathy for me growing up and I was treated like a therapist through the years. The first thing she told me when I phoned her to clear the air after I went though labour is that she was suicidal. Alongside becoming a new mum myself I now had this worry about my mum. Since this she has gave me flowers and chocolates, whether or not she was told to do this is another question. My question is , has anybody else experienced this. And if so. How do you cope. I haven't noticed this until my son was born and I can't even put into words how much this has affected me
