Weight loss struggle

Hello, I have PCOS and struggling to lose weight, I am now at my highest weight of 93kg and it’s really getting me down. I have a 2 year old and working full time so have no time to go to the gym. I have been trying different diets and going for walks but I am now just getting frustrated. I have a doctors appointment coming up on Monday going to see if they will give me Metformin or orlistat. I am just looking for a bit of advice before I go to the GP.
