First, good on you for having a successful career and for owning your own home. Regardless of whether or not you want to get out of the rat race now, it's quite impressive that you have done so well for yourself, as things like that are definitely harder for people with anxiety to accomplish.
Second, if you are in a position where you might lose money if you sell the house right now, then maybe you could consider renting it out for a year, if rental income would cover your mortgage. That way, you could get a renter in your house for a one year lease, and then you'd have a year to get your things together and really think about what you want to do. And if after that year you decide that you want to continue renting your house you could do that, and when the housing market turns in a few years, you could sell your house at a decent price and not risk taking a loss on it.
Just a suggestion. That would be a very big move to quit your job and move back home. Personally, I am 24 and I have a good career and I am looking to move out of my parents home. Honestly, I feel like a young kid in high school a lot while I am living at home. Like, I feel like living on my own would let me mature a lot. But if you get along fine with your parents and they would welcome you home, then that would be a good opportunity for you to get things together.
