Alone in Sad boi hours

You would think after spending a whole day with your best friend, you would be happy. But I don’t feel that way at all. We went formal dress shopping and she found her dress within 20 minutes and I didn’t find one at all. No dress made happy. Made me feel beautiful. So we left she was excited while I was just disapointed in myself for not being able to find anything. We then we out to meet friends for dinner. But she always invites her boyfriend to every plan we make. And he had already made me feel shitty about two previous times we had hung out and I didn’t really know if I wanted to go. We went and it turns out that he brought a friend. Who is really nice and cute and funny and I know has no interest in me but still makes me nervous to be around. And I get really anxious when being in a restaurant and on top of that he was there so I didn’t eat. But otherwise I had a good time until my best friend’s boyfriend called me out in front of everyone that I wasn’t responding to his texts(he’s trying to talk about what happened those past two weekends). I said “because I don’t want to” and left it at that. Looking back that was kind of harsh but it shouldnt have been brought up in front of everyone and thats how I was truly feeling. So we leave dinner and go back to my place for a bit and all my friend does is watch Tik Tok and text her boyfriend.
