Congrats on your 3 weeks!
I find there are people that are good listeners and good at being a sounding board. Then there are some people, who,like you described your friends, are fixers and feel they must solve everones problems. And then there are people who only want to talk about themselves.
The fixers are oftern well meaning, but I've found being skilled at changing the subject helps.
The danger of course, is becoming a bit too skilled at changing the subject and I manage to avoid coversations or advice that would be helpful. Even in my mid 40s i find myself learning basic life skills. I expect i will as long as I'm still kicking
Everything can seem like a bigger deal than it really is early on in sobriety when our emotions are still very raw and exposed. Give yourself time and space if needed. Sending my support
