Scared to drink after bad cannabis experience years ago – need advice for tomorrow

Hey, I’m a 15-year-old girl (162cm, 70kg). About 3 years ago I smoked cannabis and had a really bad reaction – felt like I was in a dream, my body wasn’t in sync, and I got panic attacks. A few days later I drank a little vodka mixed with Fun Light and after just a few sips I felt the same ‘body out of sync’ feeling again.

Since then I’ve been scared to drink. Tomorrow night I’m hanging out with two friends at home and they want to drink vodka with soda. I want to join but I’m terrified it will trigger that feeling again.

How much would be safe to try? Any tips to avoid anxiety or dissociation? I really want to enjoy the night without freaking out.
