Dose Increases please help I really need insight

So in the past 2 months I've had 2 increases. First from .50 to .75 then to .88 Now I can only drink one cup of coffee a day and feel very over stimulated when I do. Haven't noticed any lessening of symptoms and feel worse. What could this mean?

I've never gotten better after starting levo like my first 2 doctors said I would when I first got diagnosed over 2 years ago and started taking it.

Since getting sick with hashimotos I've had fatigue, brainfog, weakness, loss of muscle, anxiety, poor motility/digestion/constipation.

In the past 2 month but especially recently all these symptoms have gotten worse, especially the fatigue, I've become extremely depressed. Also I have a pressure feeling in my head along with the brainfog.. this is all really intense.

I have a young family, I can't even take my son to the playground and be active with him because of my lack of energy.

I'm so sad.. please can someone provide insight.

Could this be overmedication? What could this be?

My doctor also has me on a thyroid health vitamin.
