i know that feeling, when you reach out to people and its like no ones home. please dont see it as a sign of rejection. sometimes, when you need them the most, people get caught up in the problems and issues of their own lives. it does not mean that they dont care or that theyre sick of you.
as for the psychologist, i think its insensitive of her to not find the time to respond to you, especially after she volunteered her e-mail.
as for your friends, i think you should reach out to them. true friends are willing to listen and when you tell them how you feel, no doubt you will find that they really do want to be there for you. you most certainly are NOT pathetic. in fact, i think what youre feeling is normal. its difficult when we have problems to tell whether or not others are overwhelmed by them. i get that feeling a lot. just try to trust in how people feel about you. the ones who care want to be there. and know that everyone here wants to listen to you, so whether youre feeling alone or sad or whatever it is, share and we'll respond.
big hugs, and i hope you feel better soon.
