This is Dr. David. I am reviewing your question now and will be with you momentarily.
I am sorry you have been having bad mood and anxiety after the surgery.
you need to get your parathyroid hormone levels and calcium and thyroid hormone levels checked.
you may need to go on antidepression and anti-anxiety medications to help your mood.
medications like sertraline or paroxetine could help your anxiety and depression symptoms.
you need blood testing to find out what may be wrong with your hormones, if anything.
without blood testing, there is no way to know if this is a temporary thing or will last some time.
you can try regular exercise which can help decrease anxiety and depression.
getting more sun and light therapy could help.
the surgery could have damaged your thyroid gland which could be affecting your thyroid hormone levels
this can be checked by blood test
medications like benadryl or diphenhydramine or melatonin can help you sleep
you may benefit from exercising more than twice a week to help your anxiety and depression symptoms
you can ask your doctor about supplements such as St. John's wart which can help mild forms of depression.
getting outside more and getting more sun could help your depression as well
days are getting shorter now in the nothern hemisphere, and this can often lead to depression.
