I need answers

I’m 21 years old and been on Camila birth control aka the mini pill for about 2 years. I have been trying to lose weight for the past 8 months or so and finding it very difficult. I’m currently working with my primary doctor trying different weight loss medications such as phentermine, ozempic ( injection pen), topiramate and nothing has helped me. I’m also on other medications such as lexapro and propranolol. Has anyone had these problems and know any resolutions ?? I’m really struggling and just want to get to the bottom of this problem
