Yes, yes, yes & yes!!
Cry for no reason, hated working 12hr shifts with hardly any sleep, couldn't put a meal together, unload on husband (he isn't as patient now...). Can't drink because of meds, miss the occasional cocktail, have never smoked.
When worked 12hr shifts, raising my son, I craved alone time & rarely got any.
You are not alone, there are many of us on here who are or have been in your situation.
Say you are working on 3 issues? Think you'd feel any better tackling one at a time? Said you'd quit drinking, maybe just work on that one for now?
You do have alot on your plate, I will keep you in my thoughts.
Take care, be kind to yourself.
