Why does coffee do this to me?

When I drink coffee like it makes me feel awake so I will drink it when I'm really tired or something like that, I also like to drink it before a workout because it makes me feel energize but when I do drink it I have like major mood swings. Like it's worse then when I pms. I will feel like bawling and then I will feel like killing someone, I will feel super anxious and nervous or super excited like wtf? Is it suppous to make you feel like this? Because to me it feels like I'm on drugsand I know coffee is considered a drug but ot litterly feels like a drug that ahould be illegal lol, is this normal? Does this happen tp anyone else?
