27 F 5'3" 215 lbs wanting to get down to at least 180 lbs

I started my journey last June at 225 lbs. I was eating poorly, barely exercising, and knew next to nothing about weightlifting or nutrition. Over the course of the year I've made a lot of changes and some progress but not much progress in weight loss. I'm eating worlds better, learned so much about nutrition and the science behind exercise, and built workout routines that I really enjoy. I have even had some recomp as I have grown physically smaller by a little bit and I can lift more now than I used to. There have been setbacks though and I realized that I can't reduce my calories too far below 1,700 without having physical drawbacks (lost period, joint pain, and getting sick more often). Overly cutting my calories (tried to get below 1500 per day) has made it psychologically harder to get back onto the train of tracking my food but I'm finally getting back on it.

I know what I need to do. I need to exercise more often and I intend to hit it hard again once I finish getting moved in June. The biggest thing standing in my way is my chronic fatigue due to a childhood brain injury. I struggle to do a lot of things that most people find easy and have a lot less energy than the average person. So my question is how do you deal with not making the progress you wanted to? I know that there's more I can do and that I'm not optimized but seeing that losing a pound a week is normal is so frustrating to me because I haven't even lost a pound a month. It makes me want to give up even though I know the issue is I'm not doing it right.
