Therapy and surfacing events

Hii I’ve been thinking of finally looking into therapy after years but one thing I really really want to avoid is resurfacing any more memories cus I know this would do me more harm than good, have any of u gone about this and what are the chances it would make me remember more than I want to, I’m already really hesitant to start getting any help and this is something that’s pushing me so so far away from it
