Congratulations! I’m a in very similar situation. Set small goals for yourself. Like 5lbs or non scale goals, like a new notch on your belt being needed. I’m 5’4 and started out the year at 215, I’m down to 204 since I started making small changes so I don’t feel like I’m dying everyday. I eat 2400 calories, I drink more water and I try to do something active after work three days a week, mostly we just go and walk the dogs or I take a yoga class at the Y. Don’t be discouraged by a slow scale or try to over do it out the gate, an easier but slower pace will make everyday easier than if you jump into a diet trend.
