I am at my own admission approaching complete burnout:
I have a stressful job which I work in full time and am the main earner of the household.
Due to my husband's job I also do the majority of the childcare in the mornings evenings and weekends
I do the majority of the cooking and cleaning for the houshold including all the laundry (apart from putting it away)
I do all household admin including paying bills and organising trips away
If we do go away I pack all of mine and DC's stuff, OH packs his own stuff last minute into a carrier bag
We are also in the process of a major life event and I'm doing all the admin for this on top of the above day to day stuff.
After the birth of my first DC I got PND for which I went on antidepressants which helped. For context I have been slowly tapering them down for the last few months.
Due to the stress of the additional life change it's all reached boiling point where I have emotionally informed DH that I am drowning and need more support from him. I wrote a list of all tasks I could do with him taking on. He has now informed me that my reaction to all this life admin is disproportionate and he thinks I need to go back fully on my antidepressants (as of yet he's not completed one of the tasks I've asked him to do despite one being easily done on the way home from work).
YABU - you clearly need to go back on antidepressants as these normal life tasks should be fine to do without needing support.
YANBU - your husband needs to support you more and antidepressants shouldn't be the first port of call.
