If you tell them that you do not want them calling you or seeing you with the frequency they have been doing because you do not wish to discuss matters due to "personal reasons",they should leave you alone, at least for a time. Remember, the more you express, the more they have on you. If you tell them that you are not in the position to discuss things with them (and you can blame it on illness, depression, private matters that you are not at liberty to talk to them about), they cannot stalk you. If they try to do so, I would say something like,"Oh my, I told you brothers that I have some personal matters that I cannot discuss with you and I feel like you're trying to stalk me or something...." (Laughingly, of course)......Then reiterate in a serious way and with firmness that if there is something that you feel that you need to talk to them about that they can be assured that you will approach them and then thank them for their concern and understanding. THEN, if they try to put pressure on you, tell them that the subject is off limits and to please stop calling.
