do i have a right to be upset with her?

long story short last night i was really sad and missing my ex so i texted my friend saying that. it was on snapchat because she seems to reply to those more than actual texting. this morning she opened and only replied by sending a photo of her forehead. then she texted me on snap saying her crush sent her a gn text and she was all excited. i decided to be immature and sent a photo of my forehead as a reply. she sent me another text and she is pissed off that i didn’t get excited or want more details. the thing is she “falls in love” with a new guy every week and i’ve heard abt every guy 24/7 for months now and i suck up my sadness since i’m lonely and i act excited and stuff. last night i was just overwhelmed with being sad and tried to talk to her but she didn’t seem to care enough because she wanted to focus on what her crush sent her. even this morning i dont have enough mental energy to pretend to be happy.

i know this entire thing is petty and child like, but do i have a right to be upset?
