Yes tongue in cheek or even more direct were my words till I started to learn more about imbalances.
As for her actions brought about from alcohol vs any possible imbalance... They can be handled in the same manner... calm detachment and setting of boundaries that will keep your space at peace. When we let the actions of others get to us, we no longer hold onto our peace. Al Anon and oher support groups show us the tools we can use to keep our peace in any storm.
Yes it is aggravating to deal with the false promises but we can't control others, we can only control how we react to and towards others.
Alcoholism and a chemical imbalance are two different things. How we deal with each condition no matter what may be at the root of the outward actions we see is how we keep a control on the peace/serenity in our own life.
