What should I do this summer?

Summer just started 2 weeks ago for me and I just graduated high school, but I have literally NOTHING to do. For two weeks literally all I have been doing is sitting around the house for 80% of the day. There's not many places hiring for jobs, and my friends have been super busy lately. I'm kind of in a slump..not doing anything for a prolonged period of time starts to make me depressed after a while. Anyone wanna throw out some suggestions on what I can do this summer to at least make it memorable?
