Any advice for a beginner??(F/19/225lbs)

Hey r/fitness! As you can see, I am immensely overweight and I decided enough is enough: I'm getting rid of this fat once and for all!

As a beginner, I know some basic workouts and dietary changes necessary to aid my weight loss, but I feel like you guys may prove a bit more knowledgeable in this area. So please, drop some knowledge on me! Any advice, favorite workouts, tips or anything you feel a newbie should know, please, do share!

For those of you wondering, I have done a decent amount of research, but I personally prefer hearing success stories and results from real people. Thanks! :)
