What are some signs that i may be on the verge of having a nervous breakdown?

Nervous breakdown: This is a very ambiguous term which can mean all kinds of things to people -- yet it does not specifically correlate to any one illness or type of problem. If you're feeling anxious, depressed, having mood swings, are irritable, having trouble sleeping, having suicidal thoughts, etc it certainly calls for a professional assessment with a psychologist or psychiatrist. Help is available.

Nervous Breakdown: Nervous breakdown is a catch all term that can mean many things. Usually when a person asks this question they are feeling overwhelmed and extremely stressed. Consult with a mental health professional if you have not already so that you can obtain a clear idea of what is troubling you and how to develop better ways of coping .Best wishes.
