That is a very frightening predicament. There are always solutions. Suicide over this is a very negative step when there are so many solutions. If you could elaborate, we could talk about some of those solutions. Suicide is not one of them.

I am not suicidal, but if I could find a life light-switch, off would be great.

My partner has screwed me out of income. I am pondering a junk job. My sister, 10 years ago, took all of my family's inheritance (my parents gave it to her) and I have never recovered from that. Today, sent her an email telling her to go shove it. She wants to visit me. I do not think so ever again.

Stress upon stress upon stress.

Got worse. Now my car cannot be registered because it cannot be inspected because the tires are shit and I am agony, just spent 10 minutes screaming and pounding my chest to bring on a heart attack. I have already done serious damage to myself this way and one day it will simply happen and that will be that.

Take the job, its a start and work up from there. network with people.

I'm in a similar predicament. And the only thing that keeps me going is knowing that it won't always be this way. The only way I know that is because things are so different now for me even from 3 months ago.
The lack of financial security is always the worst stressor in my life, but I just have to keep on getting up and doing it.
I guess that doesn't really help. There is always a light at the end of the tunnel, you just can't see it there.
So hang in there and try to focus on what you can do today, not the past or the future. We can only live in the present.
