>Recently my depression has gotten a lot worse, to the point of suicide being the only thing on my mind.
Why are you depressed?
>I've been thinking a lot recently too, and I think dedicating to Christianity might lessen my depression. Does anyone have experience with this?
It comes back to the question: "Why are you depressed?"
I grew up in an athiest household, and the idea that we were only here thanks to chance, and the utter lack of purpose in life, did depress me.
>When is it too late to dedicate to god?
???
Never, you can always turn your life around.
Doesn't matter if you did bad stuff.
>How much of the Bible do you have to believe in?
Everything.
>I'm an educated engineer working with cyber security (self taught), so I have a hard time convincing my self to believe in some parts of the Bible.
Pride is the reason Lucifer fell from heaven.
Most people here will not agree with me, but I see most of the stories in the bible as things to help you be a better Christian. It does not matter if they happened or not, it matters what effect they have on you.
>Please help me, I'm lost
Only you can help yourself.
If you do not have the discipline to turn your entire life around, you will not make it.
