retreats and service opportunities

hi everybody! i’m a senior in college getting ready to graduate and figure out what’s next. i e been hoping to do some sort of retreat or service opportunity, but after looking realized how few there are (that i can find). i’ve looked into QVS, which is appealing but is really awkward with timing after graduating in may and especially with considering grad school. does anyone have any opportunities like this that they know of? are there any other young friends/seekers looking for something like this?
