Replying to What do I do?

So long story short, I moved out to Seattle with a girlfriend 2 years ago. We broke up about 2 months ago and I know nobody in this city. I work a decent paying job for being a 20 year old, but don't want to do what I'm doing forever. I feel as if it's a bit late to stay in dorms and meet people at a university, but I would like to do some schooling of some sort. I just wanna meet people and figure out what to do with my life. If anyone has some meaningful suggestions or anything I would be happy to consider what you guys have to say
