if you directly let those it concerns know how you feel (in the nicest way), im sure that everybody would understand...if they dont, unfortunately, i think you should consider them a stalker rather than a friend. if you do not want to say how you feel, you could always just reply to texts, calls and emails with a concise text/email (dont bother calling, cos that can create conversations which you obviously have no desire to have at that moment) saying that you are busy, fine and will call back when you get a chance. additionally, you can change your voicemail to say "i am unable to take your call right now. please text me if your call is urgent." this way, any genuine calls that you would wanna know about will actually get through to you rather than assuming that every call is unimportant. x
