Hi OP,h
I think there are many explanations and reasons why this school mum is repeatedly voicing this issue. Please be kind as it sounds like she is struggling, perhaps desperately so, to have reached the stage you describe. Undoubtedly her mental health is suffering. It is unlikely to come down to one thing but probably a combination of things like:
Worry, fear
Stress
Anxiety, uncertainty
Embarrassment about DS behaviour
Lack of control and influence over DS behaviour.
Guilt. Feeling responsible for the problems/ disruptions in and out of school.
Worry about the character and behaviour changes in DS, again out of her control. Feelings of loss and sadness related to these changes.
Self doubt (‘was it something I did/ didn’t do?’, ‘’am I doing the right things’, ‘is it my fault?’ etc), more guilt.
Exhaustion
Frustration
Feelings of helplessness, maybe even hopelessness if it has been going on a while.
She may (falsely or rightly) be feeling eyes of judgement on her from other parents and teachers, also family, neighbours (think of all the people your DC connect with and the number of social interactions and relationships it involves).
Loneliness and desperation.
Possible mental health difficulties and/or ND herself
The pressure of all this will perpetuate a cycle of these emotions.The longer it goes on the more she gets worried and anxious and will feel her parenting is under the spotlight. So it is understandable to see how this could be having a big impact on the mum. The situation, with the love, care and concern for her son at the centre will probably be constantly playing on her mind.
She will be trying to deal with how to manage and support her DS, whilst probably feeling like she is failing the whole time.
Please try and put yourself in her shoes and extend kindness to her as much as you are able OP. Never underestimate the power of a listening ear, it can be a lifesaver.
I worked in dementia care and understand the challenges of how hard it can be to handle repetitions and distress, and sometimes it doesn’t feel like anything can or will help. But I promise you, any time you take to listen and care, even a little bit WILL make a difference to that person. Please bear in mind others will be probably trying to avoid her for the same reason and she may be feeling increasingly isolated.
One last thing, it is a known psychological factor that witnessing the discomfort and desperation of others makes us feel uncomfortable. It is unsettling. Not a nice feeling at all. I have been guilty sometimes of changing channel when those long aid adverts come on TV as many people do because it is hard to look suffering in the face. Especially when caught off guard and your mind is busy on other things. It makes us feel uneasy, maybe even put out, and I think our instinct is to look away (ie self preserve) or move away from the thing that makes us feel uncomfortable.
I do chose to watch and donate sometimes, but not every time. Just like I don’t always make the extra time to spend with friends when I’m trying to deal with life’s challenges. We are only human, and there will definitely be days when you need/ want to avoid her OP, but if you can, try and be there and listen. A step towards her when others have kept their distance could make the world of difference to that person.
