I don't believe it is ever too late to improve your own situation. Sure, you may not be able to heal as fully as you might have if you had been able to start therapy 20 years earlier... but then again maybe that isn't true either. 20 years earlier the therapy you may have been able to get would probably have been less helpful since research and study has given us much more knowledge about dissociative disorders and trauma treatment currently. My ex t told me that many DID patients from 20 -30 years ago are returning to treatment now and are finally able to get real help. Trauma therapy has come a long way in the last five years. My T said the talk therapies and "abreaction" therapies of the 90s did more harm than good for clients with complex trauma histories. So maybe instead of being too late for you it is just the right time.
