just do not know what else to do

I am gluten sensitive - and stay low carb...... joined the planet fitness gym 7/11.. so been going 3xs a week , doing ST and have been able to increase the weights .. only doing 1 rep on each machine but feels so good - then do intervals on the bike for 20 min ........
well weight was moving a little - figured building muscle - but it has been long enough - weight should move ... last sat the scale moved .. said 211 - 6 lb loss -- so happy ... well today I finally got the courage to weigh ..........................220 WT#..........
I did have to lower my synthroid 2 xs last month - and was not sweating and heart rate lower with the exercise - now started sweating and heart rate going back up was 113- now 120 ... was 126.
so this is so upsetting I just hate my body right now and this has been going on for years no matter how hard I work at it .......... just do not know what to do - drs do not say anything .. this new one gave me a card for a pill that cost 55.00 a month with ins. hahahahasha NOT
do have blood sugars around 100 now with this new 1 x a week shot .. Byduron? (spell?) Have been on this for 8 weeks now .. feel good ..other than weight .. why wont it go down???
