How do you deal with or explain your situation to someone who says:

"Just wake up and be happy."

"You're not trying hard enough."

"You're going to a THERAPIST?!"

"You have a good life, why are you so ungrateful?"

"You're just lazy!"

I would really like this person in my life, he's my dad, but I'm not too sure I can handle his criticism along with my woes for much longer. I want to make him understand what I'm going through, so as to salvage the relationship.
