Weight anxiety

Okay, so hear me out. I know I sound crazy but lately I've been having a lot of anxiety about my weight.

I recently (in the last 3 months) lost almost 40 lbs. I was looking way better, feeling healthier and my confidence skyrocketed.

Now, almost 3 weeks ago I broke my ankle on a run and I haven't been to the gym or worked out since then. Plus, I'll admit my dieting has not been as great as it was. I gained 5 lbs back. Now I'm back to dieting but I've been feeling so guilty and full of anxiety. Every time I look at myself I feel sick to my stomach and like I'm fat again. I feel disgusting. Im at the point where I'm avoiding mirrors and I'm constantly stepping on the scale. I'm driving my husband and family crazy asking if I look fatter all the time, and they all say I look the same.

My question is, has anyone else felt such anxiety over a small weight gain? I have confidence that I'm going to lose it back but I don't want to feel like this every time I have a set back.

Any advice to calm my anxiety? And any trainers or gym people have good workouts for someone with one good leg?
