Why am I in a state of panic

Hi! I need some advice or anything honestly because I keep waking up from drinking in a full panic, my hearts racing, my mind is making up things I didn’t do, I think every word that came out of my mouth last night was annoying and embarrassing even though I know I wasn’t acting super crazy. I’m a 19 yo college student so the drinking culture is pretty intense but when I went home for break I didn’t drink at all and I had minimal anxiety. I know the root of this crazy anxiety is drinking I just don’t know how to tackle this because I want to stop drinking I just get nervous to go out sober, does anyone have tips to calm anxiety or how to go out without drinking (which I’ve done a few times before but I always feel so weird idk) also I know this is probably a weird thing to post but I’m lying in bed right now wanting to just run away because my anxiety is so bad
