I agree. Make a therapy appointment, find a therapist whose judgment you trust, and consistently go to therapy sessions. You need consistency and routine to build the core around which you would start organizing self. Do not read the DSM for the 8th time. If it did not help the first 7 times, there is no likelihood it would suddenly help the 8th time. Find a practitioner instead who would help you. Make therapy a priority. It sounds like you do have the resources for it, at least if you rearrange and deprioritize some other expenses.
