Beginning Exposure Therapy

I m starting exposure therapy next week and don t know what to expect. I m terrified that it will shatter the progress I have made this year and that it will make my symptoms worse. I don t want to bring all these memories to the surface but my therapist has told me that is necessary for progress. If you have gone through this therapy/ goin through it, could you explain what I should expect? Any advice on how to cope? Thank you
