I've texted my T yesterday, we had to fix next appt. but she hasnt answered.... its obvious and natural she doesnt want to see me anymore. it hurts, but what can i do?

my mom didnt talk to me at all today. she wanted to see if i would have started a conversation. i could feel she was doing something like this but i really didnt feel like talking at all so i didnt.... and now, at the end of the day, she has thrown it back on my face. it is not personal, i just dont feel like talking. why is it offensive to her? i just want peace and silence. im too tired for anything else. it makes me feel guilty, but why do i always have to give in to what others need and want from me?
