Mom. (Sorry if my english bad, not my mother language)

I didnt talk to my mom since saturday night, im far with my parents now, just say im a student in hospital so you know how hectic is the activity here, i dont even chat with her or my dad im not close with both i never tell them anything about me, even when im far away with them, at saturday night, i call my mom that time i just got home from night shift, my mood is bad and im not eating anything that time, my mom talking about her "awesome son" Because i feel tired , my face show it, but my mom suddenly say "just hang the phone or call later when ur mood is good, you dont seem interesting" Then i say "im tired" And she say "then dont call". That time i just hang the phone, i mean i want to call her because ive been busy and not inform her, i want to make up about that. Since then i dont call her, but my dad call me and my mom dont want to talk to me. So i just say okay, idk wht should i feel now, i just want her to know that i can be tired too, i can be sad i can be stress i can be others than always being happy. I want her to understand that i feel something than that too. I know she always praise her son, but girl im your only daughter and first daughter, dont u feel something for me? And anyway, should i call her? I mean to make up for my behaviour? But my heart feel heavy.
