When did you send your application? Why don't you try exercising? When I say exercise I don't mean going to the gym for 3 hour every day, but going for walks to the park maybe? Try eating healthier and be sure to get enough sleep. Of course there are a million reasons to be depressed when being in this situation, but you're so close to getting your DACA....Keep your head up!! And try to talk to someone about this... maybe it'll make you feel better, a family member maybe?
