Depression

Hi, my name is Amanda. I am 22 years old and am currently engaged to
be married to a guy I've been seeing for about a year and a half. We
plan to get married in Spring of 2010 as of right now. He says he was
diagnosed with depression a couple of years ago, but does not take any
medication for it. I am fraying apart. I'm not sure what to do, he is
such a wonderful man at times. Caring, compassionate, helpful,
affectionate...but sometimes he just snaps. I feel that his anger and
lack affect are completely directed towards me and therefore must be
my fault, but I know this is not true. I am a senior in college, and
am studying counseling psychology, so this is not a new or foreign
topic for me to discuss, or talk to others about/through. But now
that it's happening to me, I struggle to pull my personal emotional
attachments out of the situation and view it objectively. I tried to
talk to a friend about my pain once but it backfired on me because
they confronted him and he felt that I went behind his back trash
talking him. I just need someone, anyone to talk to, and who better
than other women who are dealing with similar situations? I'm trying
to realize that he's ill, but it's such a struggle when I feel that I
continuously get hurt from his behavior. I want my loving
husband-to-be around all the time, but sometimes I feel he gets
replaced with this cold, unforgiving, angry stranger and it is
absolutely devastating to me. I try everything in my power to keep
him happy and keep the mood positive but I don't know if I can do that
the rest of my life without any outside support. I am emotionally
exhausted. If anyone could help give advice, or just talk to me I
would truly appreciate it. Thank you so much!
Amanda
