Can things get better?

Hey everyone,

2023 has been an interesting year with quite some downs. My friends began to pretend I don't exsist, verbally bullies me. Usually I'm not bothered by such thing but since it's everyone, literally everyone (it's crazy right) it just lowers my self esteem and brought me to a lower mindset. If it were just a few people like so I wouldn't have been much bothered. They exclude me, look down on me, past me straight, looks at me not happily like a friend, blocks me out of pictures. I know the question may be, "why do you want to associate yourself with those people?", simply because I like them all. They made me really happy last year, it was so fun, I felt courage. Until out of the blue they just put this cold act. I wish I knew the reason. How it went was we all were great, talk normally, everything fun, and just straight out of the blue they act so entitled and cliquey. I had reminded myself this is for the memories, and tried not to be so caught up but they are great. My birthday is near, and I want to invite them, relive the fun moments we had. I haven't exactly spent a birthday with friends before so I think even though they put me through this, I just like them all a lot I want them to be there. If they turn me down or ignore me, I'll know who to stir away from next year, but if it's a yes then it'd be fun. But then again, I don't want to completely ruin my birthday. I've always just spent it the same way each year. Any advice with this situation and about these friends?
