Low TSH but exhibiting hypo symptoms

23yo male with hashi, 195lb 125mcg levo. My TSH is sitting around 0.2, but I am usually tired, in a fog, hair is really thin and falls out a lot, poop is usually pretty clumpy and dry, my heart rate at rest is about 55-60 BPM although I am pretty fit. My endo doesn't want to increase my levothyroxine dosage because of my TSH but I feel like I still have classic hypo symptoms... Anyone have advice on this?
