Friendship of 10 years breakup

I think my friend of almost 10 years and I aren't friends anymore. It might be mostly my mistake. But one thing led to another, and qe weren't talking for some days and now I don't think we're friends anymore, or at least we're on a 'break'

I don't know how to feel. It's as if the world was kind of bleak. I don't know what to do.

We were supposed to go on a trip together in May. I think we're still going, but seperately now, like doing seperate things alone.

I'm just not too sure what to so or feel right now. It's my most significant friendship breakup so far and I know I'm probably still under the shock, as it feels like I'm alone now. I'm not too sure what to do or what to feel. It's almost as if I'm in a living nightmare.

I know things won't really be the same again. I just feel kind of lost and I need some advice.

I'm not sure if I posted this on the right community. I just feel very lost and I don't know what to do.

It's crazy. A few months ago I was thinking how crazy it could be that there might be a future where I'm not friends anymore with some of my closest friends, and it's just crazy how I'm currently living through what I thought was so unprobable.

I just don't know how to feel. It feels as if I'm in denial rn.
