Why do (some) people think depression is something someone can just 'snap out of' (or that religion can fix)?

I have depression, quite severe, and, though I oughtn't to be, I am still surprised by the number of people who tell me to snap out of it, or tell me I shouldn't be depressed. Or tell me to 'find god' and I'll be okay.

Without my medications I become quite suicidal. Not to mention I must carry Xanax when I leave my house, as panic attacks occur frequently in social situations.

I am interested in reading opinions from everyone, including people who feel this way (but please don't be rude or nasty).

[Also a hint: Best answer goes to someone who writes educated well-thought answers, but not necessarily someone who agrees with me.]

Educated? not really.
a close family member to me is depressed and although I know better not to tell her that, I do wonder why is she not capable of "snapping out of it" or as I always think to myself: why can't you will yourself better?

By no means am I going to the defence of those who tell you that...God knows there is enough awareness out there to know that mental illness is not a conscious decision that you can turn on and off.

But still, from where I am standing, and because I have control over my mood it is hard to comprehend why you wouldn't as well.

religion can't fix it, but God can. He can make all things New
not religion. Jesus Christ. and yes if you give your heart and soul to him the HOLY SPIRIT will deliver you from depression.
I do agree that depression is not something you can just 'snap out of' or religion (I am religious) can fix.

I think some people say those things about depression because usually they have not been through it or don't understand it. I have been told that depression can be caused by a chemical in-balance in the brain which can usually be fixed with medication.

I am the same way as you when I don't take my medications I do have thoughts of suicide and wanting to just end it all.

I have had depression since I was around 13 years old I am now 24. My depression was triggered when my Grandfather died when I was 13 and I was very close to him.
Experience
Thsoe who think depression is something to 'snap out of' haven't been there and probably are not going to be sympathetic. I wouldn't listen to them.
I assume you are on medications at the advice of a doctor and it is he or she that you should listen to. Do not pay any notice to those who tell you 'god' will solve all; maybe it works for them... and fine if it does.... but religion is based on faith. In many cases, mental health isn't.
I've been depressed before and, looking back on it, I maybe should have sought help, but I didn't. I just muddled along quite miserably and eventually, in time, did come out of it (for now; I realize that it may likely reoccur). But it was not a 'snap'. It was awful, uncomfortable, and somtimes on the edge of sanity.
I wish you well. Stay true to yourself and learn to help yourself despite external judgement.
