Given your thoughts of suicide, however unlikely they may seem, I believe this is the only correct answer. You aren't just having issues at work if you are thinking yourself down that path, even in the slightest.
Also, see someone now. Things like this can snowball and it's a lot easier to become you again when you are a little depressed than when you are very depressed.
Take care.
The urge to commit suicide is not strong, it's an amusing thought that crosses the mind. I am highly unlikely to do it because I would rather kill myself for a cause than committing suicide, like getting into military and killing some terrorists. Seems I might have a hero complex :) So I won't go down and out silently.
Thanks.
I have an appointment with a professional next week. Hopefully he will be able to help.
