New again - 42 y/o with 40-50 lbs to lose

Hello! I am starting fresh again. I lost about 25-30 pounds on MFP in 2013 to 2014, went from 165 to 137 (5'6"). I felt great. I was happy.

In 2015, I turned 40. I had gained about 10 pounds but was focused on getting it off. I was working out, remodeling my house, and landscaping my yard; I was VERY active. Despite all that, I was gaining weight and felt exhausted, my body hurt, my legs and arms started swelling a lot. I joined a crossfit boot camp in April 2016. I was working out even harder and cut my 1350 per calories further. I had no appetite anyway. In May 2016, I finally went to my doctor. My thyroid had stopped working. I was placed on meds. I quit crossfit; I hated it. I lost no weight and developed shin splints that still hurt over a year later. It turns out they turned into stress fractures.

In March 2017, I saw an endocrinologist. My levels were up a bit again. I still had not lost weight. I did feel better physically, though. I wanted help and my endocrinologist suggested I was not taking my meds; oh yes I was. I wanted to be better and get the weight off. That broke me; I cried for two days. I was a failure.

A bit over a year since I first went to my doc, in June 2017, my TSH levels were finally normal. However, I had already given up on losing weight. I still walked and hiked often, but I quit watching my food intake.

I am starting completely fresh. I signed up for a new account today (I had a 967-day streak today on my old one!!!). I hope this helps. I have 40 to 50 pounds to lose. I am set up on a 1350 cal/day plan again. I still plan to walk and hike in the beautiful Minnesota fall weather. I am also signed up for 8fit (health app); I accidentally paid for a pro membership so I better freaking use it LOL!

Looking forward to giving this another go!
