Hello Bivin, welcome to Psych Central.

What you are describing sounds very much like dissociation, here is an excellent article all about dissociative disorders >>>> In-Depth: Understanding Dissociative Disorders | Psych Central In the first place it tends to be a way to cope with extreme stress but for some people can become a real problem. We also have a forum here you might like to check out >>>> Dissociative Disorders

It really is best to go and see your doctor so that you can find out what is going on, there are other things it could be and we can't diagnose here.
