I'm positive i have hyperthyroidism (i'm waiting to get my blood test done till i get over my upper respiratory infection) and i feel like im going completely insane everything just feels so pointless i snap and yell at everyone around me and i cant stop crying i woke up in the middle of the night and cried in bed for 2 hours does hyperthyroidism have that big effect on moods? or am i really going nuts? please help!!!!
