I've never heard a time frame like that before. But I don't think it matters. I'm doing my best to control myself, going to DBT and therapy, taking my medication. Slowly, slowly, life is possibly getting a little easier. I'm so screwed up though that I don't think I'll ever be normal. In any case, figure out what you want to change about yourself and work with a therapist to change that. DBT is good too.
