Hope all is well! Have you looked into online "drafting" work? Art correlates fairly well with architecture and interior design. Check out the website below, they allow you to sign up as a freelancer and eventually get assigned online work.
If you aren't too familiar with drafting, it wouldn't be a bad idea to pick up AutoCAD, PhotoShop or Revit. I think this type of freelancing/online work, would be great for you, as it is kind of aligned to your industry.
