Doctor Answers (1) on Managing emotions
From what you've mentioned, you seem to be going through a depressive episode. While depression is something that is psychological in nature, it can often be merely a manifestation of certain physical issues such as hypothyroidism. Depression is best treated with a combination of psychotherapy and medication, but only after an evaluation to rule out other possible contributing factors.
I advise you to consult a psychiatrist for the same.
All the best. Take care.
