The best advice you've received is to seek professional help. I appreciate that you don't have insurance but I'm pretty sure if your do some research you'll find a source of assistance. I'm betting that someone on the other end of a suicide hotline will have the information.
Most people who contemplate suicide don't want end their lives, they simply want the pain to stop and to die seems the only way. People with severe depression spend a lot of time sleeping (if they can manage it) because it's the next best thing to dying in terms of escaping the pain.
I'm just coming off of a sinus infection that had me up through one night in extreme pain. I took two prescription pain-killers, three over the counter analgesics and was trying everything from steam to hot and cold compresses. I ended up walking the floor moaning for hours until I got into see my doctor in the morning. A shot of antibiotics and a sinus relief medication did the trick, but I can't imagine what I would have done if it hadn't and that level of pain continued for days, and God forbid, weeks. I'm pretty sure that I would have seriously considered ending my life.
Emotional pain can be just as devastating, but like the sinus infection, it can be resolved with proper medical attention.
Unfortunately it rarely, if ever, can be resolved by simply "bucking up and thinking about the good things in life."
By all means hang in there while you seek and receive professional help, but by all means seek professional help.
If you feel so bad that you have constant thoughts of suicide, it won't go away with time and even if you got a job tomorrow or developed a great friendship next week, the underlying cause of your distress would remain.
The very good news is that it can be something as relatively simple as a brain chemical imbalance that can be effectively treated with medication, and psychological therapy has come a long way from a guy with a pointy beard and glasses sitting in a chair and repeatedly asking you how you feel. Qualified psychologists now have a good understanding of how the brain works and how you body can be physically affected by your mind. They have developed techniques for you to use your mind to overcome the problems it may be causing you.
Sometimes medications are all that is needed and sometimes it's only therapy. Often it takes both, but there are very, very few cases that won't respond to some combination of the two. So it's important for you to know that there is a way out of your pain without ending your life.
Help is out there Jay, go get it. All the best.
