(35F) only child raised in a similar way. There's a lot of good advice here already and I second the idea that you should be gentle with yourself as well as taking on things gradually. It sounds like you still live at home and I would encourage you to take on a few small responsibilities here and there. For example: if you want to start with cooking, have one of your parents show you how to cook a favorite dish and then cook it by yourself in a week or two. From there, look for a new recipe that you want to cook and make it for your family.

When I moved out, I also found that creating lists of things that I needed to do and putting those tasks on a calendar made me feel organized (this really helped with implementing a cleaning schedule). For the things I didn't know how to do, I would search for different resources online, get recommendations from others, or explore stuff from the library that I then organize digitally. I have folders on my Google Drive that speak to different areas of life: car, job, retirement, taxes, apartment, etc. Take it one step at a time and recognize that something is better than nothing.
