Hi & Welcome to the forums!

I hope you will meet many kind and good people here, for support and information.

There are RL support groups for relatives of alcoholics (Al-Anon) and I think for relatives of people with drug problems too - have you checked them out? Yup, I did a quick google search, they are called Nar-Anon, check if anything is available locally, or join those online forums too?

But if you want to work on your shyness and developing friendships etc, this forum will be helpful too!

Take care & wishing you Good luck!!
