I have a fear complex at every work and gets stressed and I think too much and gets emotional very easily, I was not like this before after my parent death it started ,i am not able sleep properly at nights ,i am able use my full potential as I was used to do before and suddenly bad habits are getting started in me something ,i tried so many times but every time the result was fail. I do not know how do I get those thoughts suddenly, if I start thinking about car and I end up seeing something which is not related at all.
