Feeling overwhelmed

Start with exactly one commitment. Log everything you eat. That's it. Make that your only goal for the first month. The rest of everything can come later. It will be easier to make changes to your life once you have the habit of being honest about logging.

Don't put a time limit on it, or choose what might sound like a long time to get to your goal - like a year. That way you don't have to calorie reduce as much. You can think of it as stopping further weight gain and slowly reducing a weight gain trend. Log your food. Don't starve yourself. Have some other goals besides the scale - fitness or macros or fitting better into a pair of pants that are a little snug now. Let yourself "mess up" and keep logging, because you've got time - a few days or weeks here and there of eating over is no big deal. Find some new foods to eat. Figure out what works for you - what helps you feel fuller, how many meals a day make you the most satisfied, when you like to eat, and when you just aren't really hungry. Find out what foods are high in calories and what foods are low in calories. Experiment. Treat it like a project not a burden. Some days you will have more time to dedicate to the project than others, and that's fine.

What exactly is it that overwhelms you?

I'm assuming you are around the 5ft mark so you are at a healthy weight .
By all means you can achieve your goal but dropping the last 15 won't happen quickly as it would for a heavier obese person.
Your deficit will need to be a small amount and you won't lose in large amounts.
As one poster suggests try just logging as your goal then see what needs to change.
Maybe working on body recomp , doing heavy lifting may give you the figure you desire without having to lose too much weight
