Life Interrupted

My life has been severely interrupted. Everything is on hold. I did a lot of work for a client a few months ago. That client is now over 70 days past due, and not returning calls or emails now (in spite of promises that I would be paid a week ago).
It's tacky to talk money, but let's just say the amount of money owed to me is what I had planned to live on for the next 6 months. Not kidding. All the money I needed for the next 6 months.
So my life is on hold. Cambodia? Not happening. Medical procedure I needed? Not happening. Nothing is happening.
I'm so mad I could could kick, cry, scream, and spit nails all at once. Why are people so dishonest?
Let's not forget this is the second time this has happened to me. My old boss, Tricia McGarry, still owes me about $10,000 for bounced paychecks. The illegal things she has done to avoid paying me and my former co-workers is ridiculous.
What I hate the most about this situation isn't just what it is doing to me. But it also hurts other people around me. I have to ask other people to have patience with my situation. I can't tell anyone if I will be here in a few weeks. The whole situation just sucks.
I'm putting a lot of energy into not being filled with hate. I don't have time for that. I'm trying to focus on a solution to my new problems. I'm hurt and angry. I worked so hard to climb up out of the unemployment hole and get back to stability. To work so hard and then be knocked down like this is not easy to handle emotionally, let alone temporally.
If I seem a little distracted or forgetful, please forgive me. There's just a lot of things on my mind right now. I'm trying to make up a new life plan, and try to find a way to be happy.
