As someone who is also suffering from low self-esteem issues for long time please see a therapist (not CBT therapy, I'd argue a lot of self-therapy books philosophically are some variations of CBT techniques). My self-esteem issues are the products of childhood abuse and trauma. I was in denial about my trauma, but therapy helped me accept the reality and work on treating the root cause, not the the symptomps. Your self-esteem issues might not root from abuse. But it's a good idea to get help from a professional. Otherwise you might be just treating the symptomps, not the disease itself.
