I would suspect that your husband's physician wants to give him samples to save him some money until he is sure the medication is working. It takes 4-6 weeks for ADs to kick in and more then that for some people.
IMHO denial is a defense mechanism against depression.
Many of the questions you have asked feel to me like you are anticipating there is no hope. The size of the pills, just look at them. Perhaps the medication comes in liquid.
You said "I'm ready to hang it up with him because he's so defensive about everything."
Would you be open to going to therapy for you, to help you get through this tough time and perhaps get a better understanding of depression?
Take care and keep talking to us.
