Stuck

Looking for a way to start dropping weight again. I've cut out soda, don't eat lactose foods, so fewer dairy items, and generally, as far as I've been able to see, I always eat fewer than 1600 calories. In any way you work out the math, I should be losing, but I'm not. It's like I am stuck.

To be fair, when I ate fewer calories, I gained weight, so that isn't going to do it.

I just got off the anxiety medication citalopram. I know my eating/ moving about isn't the issue, because I was 95 lbs until going on the medication. I gained close to 75 pounds on it.

I've lost 10-15 pounds on my own by adjusting how often I was eating instead of skipping a meal, but i'm very frustrated now. I can't do too many high-intensity things because of reactive asthma and (more realistically and truthfully) because I fell down the stairs a week ago and it's not better.

I think part of the issue is that I just moved to England from the US; ironically, the country favors high-fat foods, while they mock Americans for junk.

Any help is great. I have no idea what to do next. I hate seeing no progress.
