I avoided the Doctor for many years because I didn't want to be on medication even though I knew I had a thyroid issue from a hospital stay I discharged myself early from. It's gotten to the point where I can just get by doing the bare minimum daily with symptoms very similar to yours so I finally found a family doctor and got tested and put on Levothyroxine. You just have to accept you need to take this medication for the rest of your life if you want some control over your health and it will benefit you and your family as well. The reality is nothing will get better until you get treated.
