Hi - I am hypothyroid. Took 10 years and totally debilitating symptoms to get diagnosed. I have proved with a Rt3 test that I am not converting so I am currently on a trial of 75 Levo a day and a 1/2 T3 a day. I am three months into this and feel even worse than I did before I started treatment. However I am more concerned about a new symptom. I am normally very positive but at present I have an overwhelming sense of my own mortality. A sense of my impending demise, so much so that everything I do or think about is through a silent filter of absolute conviction that I am going to die soon and I need to have things in order. I am not depressed, indeed I should be at my most hopeful at the moment - so I cannot make sense of what is happening to me. I know I have read that people with untreated Hypothyroidism can become focused on their own mortality, so wondered could this altered state of mind I am experiencing be related to being on the T3? I am an intelligent (former) professional who is very rational, and so I am struggling with this seemingly irrational feeling. I am not panicking, but it is a highly pervasive feeling I could do without. Do others have a similar experience? Also, have others experienced a downturn in their symptoms when reducing Levo and going onto T3? I would appreciate any thoughts. Thank you.
