Freshly 21, help me out?

I’m exploring the idea of drinking after being terrified of it my whole life. I’m very very small, (5’1″, 95lbs) and have very strong reactions to weed, and medications. I always have. I have a low tolerance to everything. Does anyone have any suggestions for something super mellow I could try? And I mean like REALLY mellow. 5% or less. I know all alcohol is different for everyone, but getting over my fear is huge, and I’d like to be able to have a drink every once in a while when I feel like it.

Help me out.
