Anti-depressants

So recently I went to the doctor and got proscribed anti-depressants. There supposed to like make me more energetic and more happy or whatever and they aren’t working. Now, I’ve only been taking them for 4 days, but they’ve been making me worse. Like I can’t even smile at school anymore. Listening to the music that made me happy isn’t working. And my 5 month old puppy isn’t even working. Literally nothing is making me better. I feel like crying every second. I mean I can’t tell my mom because she assumes it’s working and if I tell her she’ll think I’m lying. I really don’t know what to do.
