DC, I am truly glad you stuck it out until you found a solution that worked. I too have had a chronic pain issue that wasn't resolved until my mid thirties. My umpteenth doctor also couldn't find the source of the problem, but he came up with a creative and effective way to manage and all but eliminate the symptoms, which has literally changed my life. I often wonder if I would have self-medicated to the extent I did when I was younger had I not had this issue.
The thing is, if ever someone I am close to wants to discuss a real life issue they are enduring, I am usually open for that. What I resent is someone I barely know "dumping" on me and trying to make me responsible for whether or not they choose to end their life, when really I have no ability to cure their issues anyway. Had you told me about your migranes, I couildn't have offered a realistic solution. I would have had to say, "I hope you find a way through it, but if you feel you must end your life, I have to choice but to accept that." Still, I'm happy that you didn't because I like having you around.
When someone is "suicidal" over relationship issues, it literally turns my stomach. I am just the wrong person to talk to about some shite like that.
