Talking Hiatus

Hi have been in a talking hiatus with my dad for quite some while now.  Maybe 3 weeks.  I don't know why I am not talking to him.  He is visiting me in a week and I don't know how I can deal with that.  It is just too overwhelming.  He has good intentions but he does not understand that i am depressed.  He thinks it is a phase and I can snap out of it and go out and things will change.  He doesn't know how depressed I am.  He wants me to work so bad that this is the only thing on his mind and I cannot work right now.  I just don't have the mental capacity to focus, concentrate or work.  I have been trying to be as communicative with him as possible but to no avail.  For him if I am not working I am not doing anything.  It is very discouraging.  I cannot make myself talk to him anymore.  It is just too stressful.  On top of that I have my mom who is visiting by me now who insists that i talk to him everytime she talks to him.  For goodness sakes, if she wants to talk to him why the hell do I have to talk to him everytime.  She is dialing him up and she is having the conversation why do I have to talk to him everytime.  It is getting unbearable especially that their arrival time is nearing and he knows that I am not happy about it.
