Overweight and obesity are extremely complex disorders, that combines genetic predisposition, changes in hormonal levels and horrible obesogenic environment that we have nowadays. There is no simple answer on how to lose weight as it depends on multiple factors too - your home and work environment, availability of stores with fresh products, your medical history, your goals in general. What is working well for one person, may not be ideal for others or even sometimes dangerous (depends on other comorbidities).

Most important part is not just to lose weight, but do it safely and maintain the weight loss. For that you need a whole lifestyle change, that is why it is so hard for many people. The major rule is: permanent dietary changes needed for a weight loss and regular exercises needed for maintaining the result.

My advise (if you are in the US) - find an obesity clinic with obesity board-certified physician, discuss all your concerns and develop a plan what will work specifically for you. It is pretty well covered by insurances and you will always have a specialist who can answer your questions and help to overcome any barriers in the future.

And remember we all are just internet strangers, take all our advices with healthy skepticism.
