Is it so difficult for women to lose weight

I see so many progress pics of men on this topic but very less of women.
I, 33F have been trying to lose weight since forever and hardly see any improvements. I have taken PT too but instead of losing I am gaining weight and no my clothes are not fitting better.
Also since I am a working mom of 2 years old I am always stressed and have cortisol.
Need suggestions on what to do. Also I manage to have decent diet.
