I think it depends a lot on whether you were anxious before you started drinking in earnest or not.
If you were then obviously there;s an issue there.
If not, then I think you need to give yourself time - 6 years more or less nightly (or at least regular) drinking if I read you right?
some people recover quickly, others take a little longer to recover physically and mentally.
welcoem aboard anyway - you'll find support here.
