Welcome to Psych Central.......i, too, have depression. i've been diagnosed with bipolarII and my lows are lower than my highs are high.

i can understand your frustration about getting a handle on it. it can be very difficult to deal with. are there any support groups in your area that you could attend. talking to people, that are in a similiar situation, can really be helpful.

i don't believe that religion has anything to do with your depression. depression is an illness. it's not a thought process.
try to find someone IRL that you can open up to and keep posting here.

there are lots of really good people here who will try and help you......xoxoxo pat
