Hi. From what you have mentioned, you seem to be suffering from symptoms of excessive worrying and anxiety. These symptoms can be due to either an underlying depressive illness or an anxiety disorder. You should get yourself evaluated and initiate treatment for the same. Regarding short term relief, benzodiazepines like etizolam can be useful. However, these are prescription medications which can be procured only on a written prescription. So, it would be advisable to meet a psychiatrist and get treatment as required.
Next Steps
