Replaced ig..

I noticed that my friends were getting close to each other now which was a very good thing because I don't want anyone else to be left out even the SPED student in our class I interact with her, but lately I've been noticing that the three of my friends were more closer, they even have the same moods and wants, especially tiktoks, they would always do TikTok videos a lot of time and picture everytime and whenever they try to join me in ofc I join even though I'm shy bc I think I'm ugly.. last time my very bff got mad at me twice and it hurt me bc I don't want them to leave me so I keep letting every hurt words go pass saying "it's just a joke lol" everytime but then i always noticed that they were always always together even chose my other friend the one I introduced to them she got more closer to my bff and our other friend, whenever I keep mentioning my crush they would sometimes say words that hurt me but I pretend it doesn't. And now they even posted IG stories with just them three. It hurts. Really.. really hurt. I feel like they just left me, and I even thought to myself, u keep saving everyone but, who will save u? I don't know who to open up to ☹️
