But don't go down that road alone. let someone in your life know you are having these problems and are getting help. Being alone on that journey is difficult. The big thing is taking that risk with being vulnerable with someone.
I've had two different close family members admitted to a hospital for suicidal intentions. In both cases the treatment at the hospital made matters worse, not better. One was 5150'd (in the state of California a patient can be taken by force to a mental health facility and held there against their will for an unspecified period of time if they are determined to be a threat to themselves or others), the other was nearly 5150'd. They were heavily sedated and given a bed at one facility or the other, medicated further, and then released without follow-up.
In both cases the takeaway for the people involved was that they never wanted to go through that again -- so next time (and there was a next time, and a time after...) they would hide it from other family members or threaten themselves or others if anyone contacted law enforcement or tried to take them to a hospital.
"Go get help" is extraordinarily difficult to actually do. The help available is almost always more concerned about short-term liability instead of long-term health.
But I think the answer is to seek help off-campus. Not to avoid getting help.
My brother went missing more than six years ago, presumably committed suicide. Going back through his emails and chat history, he constantly expressed the fact he was depressed and considered suicide. Instead, all his friends turned their backs on him and told him to talk to someone else. What they should have said instead is, how can I help?
If normal people can't afford professional help, there's something extremely wrong with your healthcare system. Then again, this is the United States we're talking about -- and socialised health care still seems to be a new idea to them.
My brother killed himself 35 years ago last week. GO GET HELP! Go speak with someone and go to a doctor or counselor. I love my brother and miss him everyday, but suicide is the biggest middle finger to everyone you know and love. It hurts the people you never wanted to hurt. Please get help not just for yourself but for those who love you.
