Hi... Speech is also a skill that we learn and once we have learnt it, it appears very natural to us, like walking, swimming, cycling, etc. Some people may phase difficulty in learning speech and may develop such issues like stuttering, etc. This can be easily sorted with the help of a speech therapist.
If you are also facing low self-esteem issues, or finding it embarrassing to adjust in a social setting, or in general phasing some psychological issues, you may seek Counselling from a Psychologist.
You have also mentioned ADHD, which is usually diagnosed early in age, but if you have any such doubts. You can consult a Psychiatrist for a medical diagnosis.
