so this is about a situation, i want to hear ur opinion

so, my friend and i were in Hackathon project. from our batch we stayed untill the last step but the last requirement for the certificate was submitting a project with group of 3 and there were 2 senior and me, my friend. the group number couldn't exceed more than 3 or less. so, the guide was telling the 2 senior to contact us individually. so, i told the senior that we will stay together and if possible contacting the authorities to see if group of 4 is allowed, and gave both my and my friends info. before giving i texted my frnd asking whether she got the seniors msg, she asked what msg and i told her about it she didn't respond ( she has a child, so she could be busy or something). after sometime, i replied to the senior and gave her both our info. my friend was taken in the group and i wasn't since there weren't any room left. however, no one informed me, not the senior and nor the teacher, she is the guide. my frnd after a few hours calls me and asks if i accepted invite, i ask which one she told me she accepted it. she can literally see that i m not in the group. anyway, she also tells the teacher and senior that I wasn't included at night about. obviously they couldn't do anything. i was just hurt that they didn't inform me that i will be excluded. i m also avoiding talking to frnd for now, cause she wasn't in the wrong, trying to avoid negative emotions, i m just feeling like it was waste of time and a bit hurt.its just i told her about everything, that senior mged, what should we do, stick together or drop out, but that day she didn't even tell me that she received invite and i m waiting like a fool until later. but whatever i m just overthinking. just wanted to get this off of my chest.
