In need of some friends/cool activities

I moved here three years ago (21f) from cali so I really don’t have much of an excuse that most newcomers do. Not exactly fresh meat lol. But I’m bored as hell out here and most of my friends have moved away to London or to other parts of the world respectively . Im looking for any social activities or cool things around Cambridge as well as any willing victims. There’s always the case of stranger danger but who knows maybe I’ll meet my best friend on Reddit
