Thanks for posting your query.
There may be possibilities of psychiatric symptoms associated with hypothyroidism
or endogenous depression
Presence of anxiety, loss of appetite, fatigue suggest the diagnosis.
You should consult with internal medicine specialist and psychiatrist
simultaneously and should go for thorough check up.
You should go for thyroid profile.
You should take behavioral therapy
and medicines for your symptoms.
You may need selective serotonin reuptake inhibitors (SSRIs) for relief of your symptoms.
