How to have better self confidence?

self-confidence: I would recommend that you see a psychotherapist. Get evaluated for add given your symptom profile. Get treated for that or any other condition present. Try not to dwell on yourself. Get out and do things for others. Volunteer, exercise, eat well, practice good sleep hygiene and take good general care of your body.
