The evidence is fairly clear - reading self-help books or using an internet-based CBT programme is similarly effective to in-person psychotherapy. That doesn't mean that these approaches will be effective for you, but they're viable treatment options that are vastly more accessible. I'd still suggest trying in-person therapy if it's available to you, but don't be disheartened if that isn't an option - there's no evidence to suggest that self-help is significantly inferior to therapy.
