Jen:
Have you ever had a mental health evaluation? Just wondering. Sounds like there might be something there (anxiety based), if you knew what it was you might better be prepared to manage your daily living without the drugs. If you are anxious about being around groups, meetings might be done by going with another same sex recovering person.
By the way, back when I got sober, in '94, I felt like a "social ******" too. It gets better, when you work a recovery program every day.
