I’m glad my reply was helpful. Was based in a mix of similar experience of raising children and DH seeming more focused on work than us (DH and I talked and eventually came out the other side) but also in having trained in (but not practiced in) therapy/life coaching.
The advice from @SurvivalInstinctsOfABakedPotato is brilliant and reminds me a little of the wheel of life coaching/therapy tool that you can google and download. A life coaching/therapist would talk you through each spoke of that wheel - marriage, career etc - and help you prioritise which areas you need to work on, formulate actions you can take to remedy them. The wheel is about balance - if you can fill up career and children but are empty everywhere else, you need to consider adjustments. This doesn’t mean filling up all the other spokes to the same degree, as that would lead to burn out, but it may involve dialling down some of the mum/career stuff to allow you space to address those areas along side them.
I also was pondering your comment that you may be perimenopausal. Have you considered booking a review at a Women’s Health Clinic and exploring bHRT (you can start this in peri) but also having a full MOT, so to speak? When I started they established I was low on Vit D, B12, iron/ferritin each of which alone can add to a sense of ennui, tiredness, feeling flat - ie make you feel something akin to being a bit depressed. When we have kids we tend to focus on their health, monitoring them like hawks, but not stopping to also ask ‘Am I okay?’ It’s a cliche, but you can only be the best mum, and the best professional etc if you are in optimum health. It’s the old aircraft safety message - you must put on your own mask before attending to fellow passengers.
Hope some of the replies here continue to help and support.
Best wishes.
ETA - am an ND mum of ND kids, too, and can really recommend being assessed as it helps you understand your responses to others, both social and emotional. It’s a bit like being given a reading glasses prescription after years of squinting and realising this what normal people experience! LOL
