Not going to give you another phone number because you seem to already have a few, and I know where you are right now.
Life is a series of experiences, you may wake up one day and look back, saying "thank you" to yourself for not ending it then. It's important to know how to "travel through time" and realize that life is combination of good and bad. We need both good and bad in order to be able to perceive good. Also, there is some truth to saying "suicide is a crime against future self".
Prison is a stupid idea, will ruin possibilities in the future, you never want your past to drag you down. But traveling or becoming a monk is definitely a better solution, more interesting than being stuck in one place with a bunch of dudes (I'm assuming you're male). The kind of people who end up in jail is usually naturally not high IQ. If you're using HN, it's very likely you are not going to fit in there, feel even more lonely at very least.
Life is an adventure, it always ends for everybody no matter if you want that or not. Paradoxically, it's one of the reasons to enjoy it.
Being depressed is a symptom, not a cause. I always view it as a good thing. When I get depressed I start changing things in my life, big time. Depression is a result of one's life being a nightmare, and I rather be aware of that than not. Do you know of those people who don't feel any pain? It sounds cool at first, but they burn themselves all the time and cannot feel symptoms of developing diseases (e.g. abdominal pains). So it's good to be depressed, that way you know your life sucks.
I remember when I wanted my life to end, I had no money to eat food, nobody to talk to, no prospects in life. Instead of looking for help and losing the rest of respect I had for myself or going to a shelter, I ended up being homeless. I can tell you that I never felt happier and freer in my life than during that time. Quickly I managed to find a job and slept in the office for 7 months. While being homeless I showered at the gym; that made me work out every morning, sometimes twice a day. I truly felt alive, my life was my own. I looked back at my life a year ago and it really occurred to me how unhappy "normal" lifestyle is, and how shitty people generally are. I promised to build my life around what makes me happpy, not around other people or what's considered "normal" or "good".
Watch Into the Wild, the story of that person inspired me a lot.
Will leave you with two quotes:
"Through every dark night, there's a bright day after that."
"Before you diagnose yourself with depression or low self-esteem, first make sure that you are not, in fact, just surrounded by assholes."
(That second one I always assumed to be corny and stupid, until learned how much negative impact idiots can make on you in life if you don't cut them off quickly).
