i love WoW classic, but I abandoned it a while back because all of my characters got stuck at a certain level - I couldn’t quest alone anymore even basic quests. Is there a guild that has people always on that could help me reach 60? Thank you so much for any help it is appreciated. Sorry if I posted this in the wrong section.
There are only a handful of guilds that play/raid WoW Classic now. I don’t know of any that always have people on.
There are many more guilds and people playing TBC Classic soon(-ish) to be WotLK Classic. If you want people to level with, you might want to wait for the Joyous Journeys Summer XP event in the coming weeks. 
it is definitely possible to do solo quests to 60 if that’s what you want. go look up some zones you haven’t been to yet
