I'm sorry to read you are struggling but so appreciate your honesty. I think you need to keep doing what you are doing, the scale will start moving again I'm sure.
It's hardto imagine that 153 was a deathly ill look, especially since you were quite happy. Maybe people just had a hard time reconciling the new you with the old you.
I think you owe it to yourself to keep going.
at a minimum you will maintain, which is always a win in my book!
