Hello, For 4 Years I Have No Motivation To The

Hello, For 4 years I have no motivation to the point here I had to give up my house, I cannot work much, and I finally found a doctor and bloodwork that shows a thyroid problem. She is sending me for an MRI, I forgot to ask what exactly she is looking for? Is there hope, I cannot live like this. I do have a vitamin b and d deficiency as well. I'm just trying to figure out what is wrong with me. I've seen psychiatrists and I'm not depressed. What do you think?
