wow, just finished reading, that is a tough story, i am sorry for your losses.
on a personal note i found hypnotherapy (not a lot of talking , good for blokes like me ) has helped.
my brother in law looks like a human version of shrek....the guys a monster...gave up a smoking habit and gambling in three sessions !. so it does work and you won't come out clucking like a chicken, unless of course you want to....!
i do not take meds because they do not work and the side effects are horrific.
i have a friend who is a doctor and also my brother owns a medical research company so know all the dirt .
congrats on the new baby on the way (i give you a blokey punch on the arm , or a manly hi 5, no hugging in this man's world. )
keep going and be brave, i believe in you.
take care
