Feel Like I'm Stuck In A Hole

I’m looking for any support or advise I can from my fellow MFP.

I was doing really well and losing up until about August of last year when I plateaued and stayed there until December when I finally gave up and took a break from MFP. I gained a few pounds back and decided to give it another go at the end of January. My body decided it was going to rebel. I couldn't keep my blood sugar from dropping, I was shaking, and exhausted all the time. I had to eat nonstop just to have any energy to get through the day. I gain a few more pounds during this time. I talked with a nutritionist and found out that the problem was that my body can’t absorb or digest most fruit and vegetables and any kind of seafood. This explains a lot of why I never felt well when I would try to eat clean. I’m also sensitive to a lot of dairy and now stick to soy milk and goat cheese. I have to take a supplement to get the proper nutrient that my body needs. I feel like I’m stuck having to eat foods that are not the best choices but what my body can tolerate.

I work out 5-6 days a week. I do circuit training three days a week(20 minutes) and I work at a stable two days out of the week cleaning stalls and working with the horses(2-2.5 hours). If the weather is nice I take my dog out hiking on the weekends(45 minutes). I’m also signed up for my first 5k run in August. I calculated my calorie count using the tdee method with a 15% reduction and I try to eat as close to the 1908 calorie range as I can. I am usually under most days. I try to over estimate the amount I'm eating and also leave a little bit of leeway to compensate for any miscalculations.

Since restarting on MFP I haven’t lost any weight and I’m lucky to lost .5-1 inch total a week if anything at all. I feel like I’m doing something wrong or maybe I calculated things wrong? I know that the process is slow but after my body tried to break down I feel like I’m stuck in a hole that I can’t get out of. I've never really posted on MFP before, just lurked around the threads, I felt that it was time that I reach out for some help.
