Need some advice

I’ve been trying to lose weight for over 6+ months and working with my doctor. I haven’t lost a pound nothing and I’m completely lost. My doctor tried medications such as phentermine topamax even diabetic medications like trulicity and ozempic. He’s also been tracking my steps every month helping me reach 10,000 steps a day. I currently go to the gym 3-4 times a week doing both cardio some days and interval training and watch what i eat/portion control (watch the carbs,not eating after 8 etc). I’ve also done every blood test there is and there’s no medical reason why my weight isn’t coming off. I’m only 21 years old 5’3 215 and worried about my health in the future since my BMI right now is 38. He suggested since we tried for so many months to talk to a bariatric surgeon. But I’m iffy about going that route. Let me know if anyone has suggestions or advice!!
