My guess is that most people feel that way. Of course you would "survive." Therapy is scary and hard, but it is also the most important and best work you can do. When you go into therapy, you only disclose what you feel you can at that moment. It is like peeling an onion....just a little at a time; you discuss that and when and if you feel more comfortable you reveal a little more. I did it in my 60's; hard but beneficial. you could also begin by writing just one sentence. We all could use some help with the past, and if you get a good therapist it will be the best thing you ever did; my opinion. Therapists understand that it is scary ad uncomfortable to open up to a stranger, but that is their job; to help.
