I've skimmed this 3 times and can't find your body weight, height, or any pics currently.
If you are very fat, just work on getting your activity level up and work on building long-term sustainable dietary changes. Watch a lot of meal prep videos on youtube. This might be a good place to start, but obviously there's a ****ton of resources on the web:

You are not a competitive bodybuilder; you need a diet that actually tastes good and you can easily comply with, but that also is conducive to fat loss/muscle building. You shouldn't feel like these changes are some kind of "suffering", but just a new thing you plan on doing for many years to come.
In this case of very fat, just have some fun in the gym, do a few sessions with a PT, try out a lot of exercises and try to get good at them(including barbells), and do some group exercise classes. Women who are brand new almost always have very strange insecurities and embarrassment when they start visiting the gym regularly, even the young, in decent shape, and relatively athletic ones. I bet a lot of them would be more compliant if it weren't for the self-consciousness. Do whatever you gotta do to alleviate this, even if that means showing up and dicking around or messing around in yoga. Your mobility/flexibility is going to be dog**** and being megafat is going to make it a lot worse and you honestly won't be able to adapt to the workload of a hard barbell training program for a while.
If you are not megafat, then start with a focusing on learning the barbell lifts as efficiently and quickly as possible so you can begin a barbell training program like GSLP.
I'm kinda suspecting from your OP you may not have the lifestyle and sort of baseline fitness where you can start a barbell training program within the next 2 weeks; it might be more like 2 months. That's totally okay. Spend a lot of time just getting good at the lifts you're going to do as part of the program with lighter weights before you formalize it in a program of progressive resistance.
