I have never heard that word, and a Google search brings up this question and others like it. I cannot find it on Wikipedia, and a search of medical databases brings no results. I must conclude that you spelled a word wrong or misheard it, as dysteria does not seem to exist.
"Dysteria" is not a recognized term in the English language. It may be a misspelling or a term from a specific context or language that is not widely known. Can you provide more context or details to help clarify the term you are referring to?
It seems there may have been a spelling error in your question. If you meant "hysteria," symptoms may include exaggerated or uncontrollable emotions, feeling overwhelmed or out of control, physical symptoms without a clear medical cause, and difficulty concentrating. If you meant "dysphoria," symptoms may include persistent feelings of sadness, hopelessness, or irritability, changes in sleep or appetite, and difficulty experiencing pleasure.
