Thanks for choosing health care magic for posting your question.
From the description that you have given, it appears that you are suffering from generalized anxiety disorder
, a condition where in there is a constant feeling of impending doom and it definitely causes a lot of distress. Clonazepam is a benzodiazepine
and is actually helpful for a short term reduction in symptoms. However it doesnt cure the root cause. You probably need a course of SSRI or SNRI drugs along with Benzodiazepine like Paroxetine, Escitalopram, venlafaxine
etc. Meanwhile even CBT is very helpful and should be tried. various relaxation techniques
, progressive muscular relaxation and Yoga are also helpful.
Hope I am able to solve your concerns.
Have a nice day!
