I think she was functional before lockdown, but recently have noticed a lot of drunken ramblings, which suggest it’s a bigger problem.does she have a drink problem?
She probably thought the poorly thought out extension was going to fix every problem in her life, and doesn’t know what to do, with the realisation that it hasn’t, so is filling that emotional hole with wine. That itself becomes habit, and I think she’s only going to get worse unless she gives her head a shake.
