Hi, This seems like an anxiety disorder and could also be an Obsessive Compulsive Neurosis... Pls approach a psychiatrist for the same. Homoeopathy has a very good role to play in this.

I am able to understand ur difficulties. U seem to have some of the symptoms of anxiety disorder. U seem to have something called as free floating anxiety. Need to also check whether u have OCD symptoms. It makes a person lose his confidence, reduces his concentration and potential. V would need to know a few more details like ur sleep, frequency, other situations that might make u anxious etc to give appropriate suggestions. Ur problem can be easily treated with counselling and if needed medications. U will be able to function better with it. Don't let ur problems affect ur personal or professional help. U need to consult a psychiatrist. U can also consult me online through the Practo chat option. Best wishes for speedy recovery!!
