Life is getting in the way of living...*hugs*
I think I may understand ... If you'd care to, this could be a great time to anonymously vent to people who want you to feel better ...
I'm sorry that you're feeling this way LTC1 
Countrygirl is right. You are not alone and what you're feeling is temporary.
We are here to support you. 
Sometimes, exercise can help - while waiting to improve your situation. It's hard to get started but 30 minutes of vigorous exercise can really change my perspective. Maybe, it could be of use for you also.
Lela -
Take some deep breaths and keep the following in mind:
You've felt this way before.
It passed.
Your negative voice comes and goes in waves. It always has and probably will until you get in control of it. You are in a strong negative wave. You know this inside and know it passes fast enough.
Everyone has an internal rythym. Ours tends to be flatter and towards the negative so we feel more sad more often. It's important to remember that the internal negative dialogue can be counteracted consciously. We need to begin to speak to our inner bummer and call its bluff. I do now and people probably think I'm nuts sometimes walking alone and they hear:
Negative Glen: "you're going to lose you know. your job - your relationship. It always happens and you know it damn well"
Positive Glen: "Shut up. We are different now. Things aren't the same and I'M in control now not YOU. I can do whatever I set my mind to and it's going to be better and very different. It's NOT the same anymore!"
Negative Glen: "you're fooling yourself. you can feel things slipping sometimes and that's always the first sign. Just pack it in and give up"
Positive Glen: "SHUT UP. I am you and you are me. We both know the meds are working and there isn't going to be that crash anymore. Things are always going to be better as long as it's the positive me and not the negative me in control. Ride it out!"
I find that if I whisper out the dialogue in my mind as I feel/hear it that it takes away it's power. No longer can it loop around when I'm suppressing it. That's essential.
Just know that there are truths you are ignoring:
You're getting help (you're here right??)
You are conscious that this feeling is wrong to you inside. It's overwhelming you and things seem very dark and far more serious than you probably think others would feel about the same events.
Failure can be defined as giving up. Are you going to give up on yourself?? You think we'll let you dangit?!?!
Chickie - smile inside a little. If you need a virtual shoulder there are plenty. Heck I have 2 available upon your request. Things always get better unless you lay down, cross your arms and give up the game.
PM me if you need to vent or whatever.
I couldn't help but notice the title in your thread. I am so sorry you are having such a rough time. What can I do to help? Do you need someone to talk to privately...I'll be happy to, I'm a good listener.
tears fall from my eyes
my heart it hurts inside
I wipe my tears from my eyes
put a smile on my lips 
I'm a master at putting failures behind me
my heart it hurts inside
You have to let it out. You've posted this in other threads and I'm worrying about you. Whatever's bothering you just let it out. I'm not sure if I or anyone here can help but sometimes just getting it off your chest is a relief and allows the healing to begin. Do you have ppl in your life to help you? I run to my mother and sob to her when things are bad and it helps just talking to her.
Trust me, I feel that way all to often myself. This can not possibly be my life, there has to be more to it than this.
I'm sorry about how you feel. I wish there was more I knew to say or do.
I've certainly felt like a failure; I've felt all alone; I've felt like I needed to cover it all up. Maybe all that I can do is tell you that I've felt that way too.
I don't know what you've already tried to help yourself. I know that sometimes it can seem like everything has been tried.
In my case, I got to a point where I had to somehow get my own spirit back.

Lela, I'm so glad to hear your feeling better about things. You certainly sound like your in a better frame of mind.
I hope you're hired for the job and good luck with the court case.
When I lived with him, I had a break down. I lost my job. For two months I sat and stared or slept. I could not express myself verbally. I didn't even get dressed I stayed in my pajamas.Thanks to all...I'm feeling better...I had a good job interview...I still have a job...Legal aid said to counter sue my ex boyfriend. I'm giving it all to God. What will be, will be!

Glad to hear you are picking yourself up and dusting off. That's the way to go.
I'm glad too I'm in Canada as when you sue and lose here you have to pay for all the other side's expenses. That keeps these grudge suits down to a low growl.
The guy should have just walked away and wrote it off as a learned lesson. I can't stand whiny men who feel they need revenge.
