Getting started (again)

I am in my 48th year trying to pick up after a total abdominal hysterectomy on 1/9/18. I lost 35 lbs from 2015-2016 and maintained that weight loss until I started having multiple medical problems for the most of 2017. I powered through workouts until 9/17, but lost motivation once pain became too much to handle. Found out in 12/17 that I had four fibroids and that my uterus was the equivalent of someone who was 24 weeks pregnant. Fast forward to present - I am ready to get back into the gym and methodically change the food choices I make. I am resigned to login every day to MFP and log every single bite. My doctor released me to return to work and exercise on 2/26/18 and my new starting weight is 212 lbs. I am focused on my next mini-goal of 199 lbs. I would love to be back where I was before I had my three children (160 lbs), but feel I need to be realistic. I am setting weight loss goals in increments of 5 lbs, reach goal, and reevaluate until I feel healthy. Maybe I'll get to 160, maybe not. Weekends will be the hardest as my boyfriend and I tend to go out, but he is jumping on my wagon to make sure we are doing this together. He is already a lean and active guy, but it is his support, motivation and encouragement are making this a lot easier then when I did it alone. Love a workout buddy! Wish me luck!
