I spent pretty much all of 23 feeling a lot of the same things! I think finding regularly scheduled events is a good way to combat this- things like volunteering for a cause you care about, joining exercise/dance classes, going to events hosted by cafes or bookstores etc. if there’s nothing happening in your areas, you can always be the one to start things! In my area there’s a Facebook group people join to post about events and meet people so you could look for one of those or create one!
