OP I get your fears I really do but I also think this is a very complex issue
Here's my situation...I was a senior manager not only in rank but in an industry that capitalised on the tough talking no nonsense kind of image. I was and am as tough as they come and prided myself on it....I explain this so you can see the mental image I had of myself and that others had. I regularly dealt with dangerous and risky situations.
I was also massively motivated by the social conscience side of my work....making my little corner of the world a better place it was part of my identity (still is)
My dh is massively supportive and we are very much a partnership of equals. I'm very lucky
But when I became a mum the first time there were some serious shocks
(Before I get flamed dh adores his children more than anything) I realised there was a difference between mum and dad ....when ds1 cried it physically hurt at first ...instinctively I jumped to him (still do most of the time)....the thought of him not being OK made me internally shake. It was partly hormonal led and partly reality.. dh didn't mean to but occasionally slept through him waking which was and is beyond impossible for me.....something almost primal kicked in (probably should have guessed that when I unintentionally growled at the paediatrician when he tried to take him to be checked lol) so it did mean that I did more of the child care
I did lose myself very briefly after ds1 but I realised it quickly.... and the key is here that I didn't find the old me....I found a completely new one and one I love
I now have another ds2 and again things were initially very based around me and yes the identity expanded to include being mum as well as an ass kicking dynamic career woman
I guess what I'm trying to say is there are times I have doubted myself and lost my way but I found it back and it added to my identity it didn't take away from it
Despite the pressure to be a single image ....I. e. Mum OR career woman , that's not true....but you do need to accept there are sacrifices for that
I both need and want to return to work....I have the higher earning potential and the boys need a better life. Plus I am good at what I do and I love it. Unfortunately at my level there are basically no part time jobs. It's full time or nothing .... so OK so be it
One of the sacrifices I have made is accepting that others will judge and God knows I've had enough of it....ds2 was seriously ill at birth as was I. ...and I've been told more than once how awful I am for considering working full time and don't I appreciate I could have lost him
Damn right I know I could have lost him....it was me sat next to the incubator...no other fucker. ..it was me that sobbed for two hours after I consented to the lumbar punch that put my newborn through he'll less than 24 hours after his birth when I was unable to be with him (i had blood being pumped into me and was rushed back into icu)
Point is...I've had a load of crappie but that's the price you pay, as well as a tiny guilt voice in your head.....but the pay off is my children are happy and so am I. ...I'm proud that my children will know I am an autonomous person , they already ds1 know that I adore them more than anything but that doesn't mean I stop being me
I would go so far to say I have found myself as a mother because I know exactly how strong I am now and Damn if it isn't a hundred times stronger than I was before
You may well lose yourself but what you will find is something amazing....I know you didn't mean the dusting comment as it was taken but consider this....yep now I'm at home until my job starts....I do clean three times a day...not because I give a hit about my house frankly but because I need it to be sanitary for the boys , you don't become a stepped wife unless you want to (and if you want to ...by all means cracking on....do you ...whatever that is)
But be prepared ... most other mothers are fantastic supportive and fighting the same battle to be their own person....but there are judged pants and there are those that will insist that you fit a stereo type
Stay strong and know that by finding your new identity as both you , a mother and a person is the best for you and your children
Sorry for the essay but it's a topic I feel strongly about xx
