At this a long time and feeling really deflated

Hello, I have had myfitnesspal for 10 years, two years ago I hired a coach and in fairness from feb to july, I lost 20lbs but since then I have been up and down. I did hyrox sim in August so that was my main focus. since September I have put up half a stone. I am thinking of weight management injections in the new year which I really don't want to go down that route. I have 5ft 4, 46yo mom of two small kids and 168lbs, my coach has me on 1700kcal, and I hit 100g protein most days. I do S&C twice a week and 45 minute cardio once a week. My steps are down to 7000 per day, it used to be 10k last year! Life is stressful at the moment.
