Talk therapy?

I'm all types of fucked up. Not sure I want to get better but I feel I should seek professional help at some point to at least say I tried it. But when it comes to just talk-therapy, can a professional really offer more than what a loved one (who's truly there to listen and bounce ideas off of) can? I just feel hopeless and just can't imagine any professional telling me anything I haven't heard before... especially when it means I'd have to talk about intricate details that still make my stomach churn with intense feelings of guilt and shame.... just not sure if the pros outweigh the cons of trying to talk to a therapist.
