A year ago i was diagnosed with hypothyroidism and was put on .25mcg on levothyroxine. I took it for about a month or so and stopped taking it because it was expensive and i was bad at remembering to take it. I've noticed for a while, like ever since i stopped taking the meds that i have been really tired and have been sick alot with sinus infections and bronchitis. I am also quite depressed and feel like im at a loss. I have had a sinus infection for the last 2 weeks and seem to be getting them like every 2 to 3 months. I also have gained some weight. Can the illness i am experiencing be an effect of me not taking my medicine. and should I go to the doctor to get another blood test since its been a year since my last test was done. Also could taking thyroid meds possible help with my depression or should i get some meds for that? Im really tired of being sick all the time and depressed. My current doctor hasn't even sent me for an allergy test even after noticing all the sinus infections. Any advice on where to start?
