Hello there.
I myself almost committed suicide last year. Please continue to reach out and get help. I know what gave me hope was that a lead reached out to HR on my behalf when I confided in him. Sometimes what we really need is to realize someone out there just cares.
I also went to a site called metanoia and it helped (sadly I can't post it because I have too few posts, and there is anti-spam filters on this site; hopefully the admins can allow certain sites to be posted at any level in the future...).
The site helped me to realize how suicide worked. That my coping mechanisms had reached the limit, in regards to the situation I was dealing with. And if you can't carry the burden fully yourself, that is where others do need to come in. Because what you have now is not your normal knapsack of responsibility and worries, but a boulder crushing you. Let others help you carry this boulder or help you chip away at it.

Please, please don't give up.
P.S. Please respond so we know you are okay.
