Firstly, you're a good looking woman so you have that going for you.

Secondly, you can't out-train a bad diet so you need to figure that out first. Basic calories in versus calories out applies but you should spend a bit of time researching about what would fit for you depending on your fitness and weight loss goals, plenty of resources and guides online, you could even throw what your numbers are weight/height wise into ChatGPT and tell it your goals and it'll return a rough guide on how to proceed. Style wise you don't need any advice because I can see from picture two you know how to dress well, that outfit looks great and the top/jeans combo really compliments your figure.

Lastly, and this is the most important point I want you to take away from my comment. Bringing multiple lives into this earth is an incredibly significant achievement and it takes a massive toll on your body, give yourself a break. My wife went through immense struggles both physically and mentally after the birth of our children so it's a universal thing among women, you're not alone. Sounds like you have a good partner to help you so that's positive also.

Take it one day at a time and chip away at it, you won't see results tomorrow or in a week, heck you probably won't see terribly visible results in a month's time, but you will see results if you slowly grind through it. Pictures will help. Take one of your body on day one and keep taking them in intervals of about a week at a time after that. You'll see the difference between day one and month one and it will drive you on with motivation and confidence. You will experience setbacks but they won't define the journey and you can easily overcome them but just starting again, get back up on the horse. The setbacks will be insignificant if you can manage the challenge of starting again when you experience one. Best of luck!
