I’m a lightweight when will I stop being drunk?

I took a big shot of tequila today around 3 it was reposado I believe. I just started feeling really drunk. I haven’t really been drinking water and I only ate twice. Both really small meals. I hate being drunk when will I stop feeling weird? I just downed 2 30oz tumblers of water just now. I’m scared and anxious thus why I don’t drink.
