Feeling of unbecoming & losing I-hood

There is an entity called Rohit (knowing subject) who has his own liking, disliking, habits etc. Or maybe these liking, disliking, habits etc make up the entity called Rohit. By constant awareness of self identification ( and eliminating things which I'm not) , I have started losing I-ness. It is difficult to explain in entirety but it is like death of the entity. Although this death of the entity giving a sense of peace and thoughtlessness, but it has started giving fears also. Fear of losing self - all liking, disliking etc along with social associations. It's kind of void & nihilism. It's like vanishing of selfhood & my own existence. So, my question is what should I do in this situation? Why it is happening? Should I go ahead against fears & continue my endeavor of non identification or I should step back (stopping the meditation & start identification again)? Or If I continue in unbecoming, what are the suggestions would you give? Note: I'm aware of paradoxes I used while posting details, ignore them as there is no any way to ask other than using 'I' wherever required.
