HELPPPP ANXIETYY!!!!!!!!!!!!!!! SUGGEST DOCTOR

My father is going through severe anxiety, and his mind is constantly filled with negative thoughts that are making it hard for him to go about his daily life. He feels restless and overwhelmed, and no matter how much he tries, he can’t seem to escape these thoughts. To cope, he has started drinking alcohol, believing it helps him feel relieved, even if only for a short while. But I’m really worried that this will only make things worse in the long run.

Please recommend a good doctor who can help him overcome this.
