Ahuax, I actually took your advice with grains quite literally and strongly - it sounded very intelligent to me, and I use it almost on a weekly basis.
I only eat granola bars now (fully germinated, I know) but I was definitely going to make a small hydroponics garden when I have space and money, and eat small budding plants from it because it seemed so logical

.
I think you are lonely ahuax, as we all get from time to time. Sometimes it lasts a long time, and it will test even the most logical. But don't be afraid, don't fear lonliness, for when you believe you are alone, that is the only time you are alone. It is a catch 22, you must not think about it, but in order to not think about it you probably will, but again... you'll see the end of it.
As for suicide, I don't know why we got the idea to kill ourselves (as a race) its odd to me. I've felt it too - I've never thought of actually doing it, but man does it seem great at times right? But then I realize how warped my thinking was at the time, how high I was on the naturals, I couldn't even realize I was thinking like that.
Ahuax, you are very smart, but I think you have alot of time on your hands, and alot of time, and alot of thinking, with a bit of lonliness mixed in is never good. I would definitely be a friend of yours, in fact you sound exactly like 3 of my very close friends. I think they're crazy, but I love them for that. They think for themselves, and they can endure anything.
It will go away. In time. Keep growing your plants, and eating healthy, there is no cure for your thoughts externally, that was my downfall - the cure for your thoughts is completely internal. Good luck buddy, we all keep you close in mind and heart.
