I'm sorry it's this way for you Hun.
Our addiction/alcoholism got easier to deal with once we got our meds right, not that we aren't living the perfect life of sobriety, but it's not as bad where I had to drink and drug. Today it's more like trying to relive the glory days, but usually fall flat and it's easier to sober up now.
Med maintenance is a constant thing, and skipping on meds lessens the therapeutic effects.
I'm sorry about the infection, that has got to be awful. Hang in there and I hope it gets better for you.
