OKAY SO....this might be long but I really really really need a second or third or fourth opinion on this!!
Sooo basically I started dieting/exercising when I was 13, then started restricting back when I was around 14. So I restricted/exercised all through high school, dropped 40lbs in like 6 months because I was barely eating and exercising (got down to my lowest 95lbs). So I was maintaining and not losing on like 300-500 cals a day after I lost all of that weight. Then I started my senior year of high school. At the beginning of my senior year, it was almost like a switch went off. Neither my diet nor my exercise routine had changed but I noticed that I had gained weight. I didn't own a scale at the time, but I would go to my grandma's house very often and weigh myself there, and I was 10 lbs up and it was like where did that come from???
So this weight wasn't going anywhere but up. You guys, I'm not even fucking kidding....I gained an average of 10 lbs A MONTH. No binging, in fact I was eating LESS, and still working out, if not MORE, I even got a gym membership. This was very stressful because despite my efforts, I was literally gaining weight overnight, my clothes weren't fitting me anymore, graduation was coming up, I had missed so much school because I was so depressed, but I did make it through. At this time I was about 150lbs.
I did actually go to the doctor (we didn't have insurance at the time, in fact we just got some like a month ago lol) and got my labs done, they called me and told me everything looked "fine" like ugh, of course. So I just shrugged it off and thought, 'hmmm maybe my body is telling me it's time to recover?' but that doesn't happen right? I was watching all of these YouTube fitness videos about "how to kick-start your metabolism" and workout routine videos, and I was avidly going to the gym, trying to do like strength training workouts. But it literally didn't matter what I did, I was still gaining and ended the summer at ~190lbs. And no, it wasn't muscle, I was actual fat. So I got a personal trainer (lol that was a shit-show), got in a car wreck, was broke, and decided to join the navy all in the same month lol. Anyways to make a long story short: I trained for the navy (working out 3-4 times a day and eating maybe oatmeal or an apple, lost like 15lbs in 3 weeks) I didn't join the navy, went back home, was still training and everything, ended up pulling the muscles in my inner thighs (idk what they're called sorry) from running, and decided I didn't want to join because it was so stressful and overwhelming. So then I gained ALL of that weight BACK....ugh. So after about a month and a half from not working out, the pain and inflammation was gone I started moderately working out again. Started to eat normal over the months to 'try to increase my metabolism' got up to eating 2000 cals a day.
So for the past year I have been eating 2000 cals a day and working out here and there to be healthy. So anyways about 3 months ago, I decided to start a diet/restricting cals to see if I could lose a bunch of weight because I am literally so uncomfortable with my body. I've been eating about 600-1000 cals a day, buttttttt I haven't lost a POUND....I mean like I don't lose weight when I try, it's literally the opposite. I am wondering if all of my dieting over the years has caused me to develop underactive thyroid. I'm just worried if I go to the doctor and they do lab work, they're going to say everything looks fine even if they do a full thyroid panel...I don't want to be misdiagnosed, and I don't want to waste my parent's money. But it's like I don't know what it could be or if I can fix it on my own? I mean I don't know any other explanation for gaining 100+ lbs in a fucking year, and working out and eating healthy and not losing a pound? And I have other symptoms besides the weight gain/unable to lose, like: HEAVY periods, headaches, muscle cramps/weakness, chronic fatigue/tiredness, I got the flu three times within 5 months, anemia, really really bad depression to the point of suicidal thoughts/self-harm. And it's just like obviously I have a "sluggish metabolism" but would it be considered "hypothyroidism" ? Should I seek professional help or should I try to fix this on my own again? Sorry if this is long, I just wanted to include background info, and I even revised this, it was longer, lol, but please leave comments/feedback!!!!!!! <33333333
