entropy I hope u wud have found some solution. But I will suggest, as it may be helpful to you or someone else. You can go to Dr. Arman Pandey, he is Clinical Psychologist, trans friendly, very knowledgeable, so he can provide you with the Gender Opinion certificate, if he finds fit. One more thing he is from Mumbai, but he does online consultation, so I guess location should not be a problem. But I am not sure about how transition with teen, but in your post, u mentioned 17, so soon u will be 18+, but you can start your session now, to get mental help. I had a personal experience with him (online). If required I can DM his clinic number to get an online appointment. All the best for your journey!
