Look, I'm gonna be real here. I think you're too wrapped up in yourself. I'm gonna sum up all the stuff I've seen here and that's what it comes to be to me. You're very self centered. Maybe because you've been injured in life - I have been too -but...so what. At some point we have to grow up and other people and responsibilities have to come to mean MORE THAN WE ARE ON OUR OWN. I think we have to stop thinking about ourselves and put other people first. Your first thought from now on should be.....how is t his going to affect my husband. My kids (I forget if you have them). Or whoever is involved. Not...HOW DO I FEEL....NO NO NO. Forget about how you feel. You think too much about how you feel. You need to start thinking about OTHER PEOPLE FIRST. And what they need and what you can do for them and how they feel and what your responsibilities are towards them and the world. Many of the problems of the world become solved when we get out of our own heads. This is not just you, this is a societal problem where we have become too focused on ourselves as individuals and we psychoanalyze everything. Get out of your head and do what has to be done. I think the more you get into this kind of thinking about others, you'll find that your life situation will start to improve. And if you have emotional reactions to various things in life as we all do....just let them go...just say...this is an interesting thought or feeling. What else can I do? Don't ruminate on things, it doesn't do any good. You just turn things over in your mind over and over, just let them go, free them into the wild. Go DO something positive for someone else. Maybe even an advice post online!
As for suicide, most of us think about this at times, especially when real problems hit - especially illness. Nobody wants to talk about it, but we all think....what if I blah blah blah. But if you do that....well, the whole game ends, you give up the opportunity of something good happening, of doing something better, you give up tomorrow....it's not worth it. Whatever you feel or think when you're at your worst, it's still temporary. You can feel better and you most likely will. Don't give into the worst things your traitor mind can concoct. Think about the best things that could happen. You might be surprised at how life can change, sometimes with small efforts. But you have to appreciate them. And you have to take the best physical care you can of yourself because if you're tired, run down, malnourished, whatever, it makes it harder to recover. Always think it terms of recovery because nothing in life is permanent including life. Things can always get better even if it takes some time.
I don't know if this helps at all, but I wanted to pass it on to you and maybe you will get some value out of it.
