Friend issues…

I'm sorry I'm not really understanding your situation. What do you mean by "walking too slow"? If they're walking slow why don't you go with the flow and walk slow with them. By walking slow, you get to talk to them and hang out with them longer. And for that "someone" that you cannot stand, you should talk to your friends about how you feel about that "someone" and if they are still hanging out with that "someone" I suggest you not hang out with them when they're with that "someone". (sorry, that sentence sounded funky lol). As a true friend, you shouldn't force your friend to pick side. There are always certain people I can't stand but I don't make my friends hate them too. They have their own mind and opinion about someone so I shouldn't force them to follow me.

I think you should just give them a friendly nudge from time to time? Maybe say things like "come on we don't want to be late" Honestly, I think it depends on what kind of people your friends are. If they're really chill people you could tease them a little like "hurry up slow poke" or something like that?

I'm sorry for your current situation but I can understand how you feel. I used to feel like that with my old friends, I hate walking slow, being late for class, and them being friends with someone I hate. I get it. I also have really bad anxiety. What I suggest is, I know its hard, but make new friends but don't just drop your old ones too quickly hang out with both "groups" and if your old friends just keep fading slowly and subtly drop them.
