Third Order Carmelite here (Ancient Order, not Discalced) from the Province covering your area. My best friend has a disability, actually a number of them, which affects her alertness and ability to keep up with the rather heavy prayer regimen we ask for. However, all requirements have the caveat, “according to your state in life.” One is not required to do the impossible, at least not in our Order. She cannot go to daily Mass, she cannot always keep up with all the liturgical hours of prayer, but she is still progressing just fine in her formation and has just been received into the Order.
My advice to you would be to consult an experienced member of the OCDS, particularly someone in formation, for information about how to progress from here.
Be at peace.
