Welcome to SR Ktulu. Glad you've made the decision to quit - I can pretty much guarantee no one has ever regretted the decision to NOT drink ;-)
The alcohol in Jaeger is exactly the same as what's in beer or wine or whisky...so that's likely your addiction telling you that its 'just the jaeger". I was quite successful in destroying most good things around me just by drinking beer - and drinking mostly at home at night. So it's also likely your addiction trying to tell you that it wasn't so bad compared to others.
As far as recovery goes, group meetings are only one of many options. There are recovery plans that are very personal and there are communities like SR that are virtual. There's therapy and counseling too - and if you have anxiety i'd highly recommend at least talking with a counselor for an initial assessment - I waited until I was in my mid 40s to do so and wish I would have done it far sooner. There are a whole host of ways to make anxiety more manageable.
But again - welcome and I hope you can join us for some more conversation!
