Lost it, gained it, now I'm back again

Hello! Last year was an amazing year for me in lifestyle changes. I had dropped 45 pounds and had started weight lifting and crossfit with my husband, friends and family. It q's great! I even gained quite a good amount of lean muscle too!! Around the end of last year I had to have my gallbladder removed, u didn't have pain but I felt constantly ill, it was affecting my liver. After surgery, I have continued on my earing habits and weight training, but I can't loose the weight! Infact, I've gained about two pounds even month or so since then and I can't loose it. So I'm here now, on fitness pal hoping to find a solution and get back on track!
