Need a recommendation for a psychiatrist

I am posting this on behalf of this user : u/saint_nukes Hey guys, I really need your help. Can you suggest a good psychologist or psychiatrist in Chennai? I have a friend I’ve known for nearly 19 years, and in just a few days, he has changed in ways we can’t even recognize. His fiancée, who lives just a couple of kilometers away, was the first to notice and inform me a week ago. When she told me his attitude and behavior were shifting, I brushed it off, thinking it was just work stress, since he owns 3 businesses. So, I even encouraged her to spend more time with him have dinners, go out, keep things cool and normal. But this morning, I got a call from her, and what she told me sent shivers down the spine. He started blabbering things that made no sense saying they needed to abort the baby, that in the future, she was going to be a single parent, and that his life insurance would go to her, but it wouldn’t be enough for raising the child. The most terrifying part is She is not even pregnant. Then, in the afternoon, out of nowhere, he had an argument with his dad over something as simple as skipping breakfast and dinner today. His anger elevated so fast that he started throwing things at his father and, in a fit of rage, accused his late mother’s sister, who lives with them, of being responsible for his mother’s death. And His mother passed away from breast cancer. His dad and aunt told me they noticed something strange his hands were shaking, he was sweating like he was terrified of something or someone. I don’t know what’s happening to him, but I know this isn’t just stress, though I'm not in Chennai for now. In sure This is something deeper, something serious. Please, if any of you know a good psychiatrist or psychologist in Chennai who has handled similar cases, let me know. I just want to help him before things get worse.
