OP First STOP listening to others negative comments.
STOP looking to your rather selfish DH for understanding.
FIND like minded mothers and speak to them.
This is what l wish someone had told me when l really hated being pregnant and had some of the same worries as you:
Take a calm look at all the most successful women you admire in the public eye, and if possible in jobs such as you previous one.....do some have children ? YES of course they do.
Are they all fat and frumpy...NO
Do they all wear terrible clothes, have bad hair and are generally a mess...NO
Do they generally seem to love their children and life in general..YES
Most women have children, many have good careers, are still gorgeous, have a social life, time out with friends, great hair, and remain fiercely ambitious.
PREGNANCY CAN BE VILE, BUT DOESN'T LAST FOR EVER.
HOW YOU LOOK AFTER IS DOWN TO YOUR OWN DISCIPLINE.
YOU WILL PROBABLY FIND YOU UNEXPECTEDLY LOVE YOUR BABY MORE THAN ANYTHING, AND HE/SHE GIVES YOU JOY YOU CAN'T IMAGINE NOW.
DO MOTHERHOOD YOUR WAY.
Read the above several times a day!
Stop feeling resentful, you have gone down this road and now need to start looking forward.
You cannot solve all these issues at once. So for now forget thinking about work that can wait. Just remember you can get back there.
Without trying to elicit support from selfish DH, (waste of time) try and find positive people you can talk to, anyone else avoid.
Do a relaxation CD at bedtime or when you feel really overwhelmed.
Focus on getting prepared for the birth and coming home after the birth as this will happen soon. Get help in place, solicit favours from friends/ family to help you, get food prepared, treats for you whatever that may consist of.
Try to change your mindset from fretting over the things in the past you are unhappy with to how you are going to cope with this new chapter YOUR way. Focus on this for now.
Lastly Prenatal depression is common and can make it impossible to see the positive in anything, you may have this but if so it will lift as soon as the baby is born and you may feel much more yourself.
I felt very much like you re loss of independance/ freedom etc and panicked through my first pregnancy feeling dreadful, but l can truly say my 2 DCs have made me happier than l could have ever envisaged.
I have still worked at times and have attained the same weight as before DCs.I still love fashion, days out without Dcs, nights out too, it is all doable.
I don't expect you can feel better so heavily pregnant right now, but you are nearly there and trust us who have been there, it gets so very much better.
