Thanks for choosing health care magic for posting your query.
From the description that you have given, it appears that you had a hyperthyroidism
for which you have taken proper treatment. The symptom of tiredness
that you are stating occurs cause of hypothyroid state and hence you should re-check your thyroid state. Probably even a TSH level
alone will also do. Secondly, both hypo and hyper thyroid state can lead to depression
and the same should be evaluated by your physician/psychiatrist
Hope I am able to solve your concerns.
If you need any further help in detail, I will be more than happy to help you.
Wish you good health.
