First, I am sorry you are in this position.
You have gained valuable experience -- both in IT and business. The key is finding the right business that values what you have to offer.
In addition, you also have transferable skills: problem solving, analytical reasoning, critical thinking, adaptability, project management, teamwork, communication, writing, listening, creativity and attention to detail.
One option to freshen up your resume is to take some classes from IBM Skilsbuild. There are a number of good course that are free.

There are courses on AI, Cybersecurity, Data, IT Project Management and more.
My guess is once you complete a course, you'll get a big sense of accomplishment and a boost of confidence. You could also earn a digital certificate that you can add to your resume. It is also a good talking point in interviews to say you are a life long learner and keeping your skills up to date.
Pulling for you!
