I know that I haven't been through everything or, I believe, even a fraction of what you have.
But, I am so sorry to hear that your feelings are so painful and frightening. I can understand how you feel about being stuck, and being scared in the early hours of the morning. Please remember and believe that, for whatever it may be worth, you are not alone in those feelings.
I thought I was just coming down with a cough or a cold, and my employers are not keen about sick leave so I struggled in last week, hoping it would run it's course, and I wouldn't have to deal with the department's almost-incomprehensibly-self-contradictory-yet-always-somehow-genuinely-threatening sick-leave policy. But, I felt so bad on Monday that I had to call in sick. Consciously, I know that my manager IS overworked and IS stressed, ( He has tension headaches that he tries to cope with in the workplace without anyone noticing, poor guy. ), but I confess I wasn't exactly " feeling the love " from my employer during that conversation. Anyway, turns out I have a chest infection in my upper right lung. In fact I'm just on my way home from a precautionary chest x-ray at a local hospital. And, I'm on antibiotics so strong that they might well have a " street value "!

So, I'm feeling ill and tired myself at the moment, which is amping up my depression and anxiety, and also my regrets over chances that intellectually I know that I never had. Does that make any sense?
I applied for a wide range of jobs over the years, never turned a job down, and yet here I am stuck in an employer whose main thought seems to be " payroll reduction ". And, at night. when I can't sleep and can't stop coughing, I find myself worrying about and dreading the obligatory " back-to-work interview ", where I have no idea what to say. Am I meant to apologise for being ill? Or, promise never to be ill again? What is a practical, rational approach to an irrational process?
I sit up in bed wondering if there will come a time when I might be ill one time too many, and I'll be " slid " out of the department and lose my job. Or, perhaps I just won't be able to keep fighting, to keep swimming against the tide. And, what other jobs are there for anyone at the moment. And, I wonder what I did wrong to be alone now. With no girlfriend or confidant I can turn to in those early morning moments, at those moments when my SI, is so persistent. When thoughts of suicide are, God forgive me, almost a comfort, offering at least " a way out of the woods ", if things turn out as bad as I fear. Although, at the same time I know intellectually that that's just " the depression talking ". And, logically, it's extremely unlikely that it's even possible for things to turn out as badly as I fear. ( I have quite a vivid imagination, particularly when I'm scared in the early hours of the morning.

Sorry to go on. I so don't do brevity!
But, I can say that I do know how " scared at 1:00 in the morning feels. " You are genuinely not alone in those feelings.
So let's you and I both hang-on, huh, ( Obayan )? What do you say? Please hang on, there ARE good people in these world, they are everywhere to be found, eventually. As a friend of mine at work, Michelle, says: " There are angels in this world ". This faith, this personal experience, helps and comforts me. As I hope it will you.
As for me, I'll rest, rally some Celtic stubborness, give the antibiotics and cough medicine a chance to work. And, God willing, hold fast to the real possibility that there are friends I haven't met yet, a job where I could truly belong, feel comfortable as myself, and make a contribution. You never know, I might even find " true love " yet...?
Please do keep taking care of yourself, (((( Obayan )))). When I'm lying awake coughing/worrying/regretting I'll send good thoughts your way! God willing, let's both, and everyone else on this site, find our way to better days!
( As far as " the girl of my dreams " is concerned...Does anyone know where in South Wales I might meet truly desperate and vastly patient women who like Science Fiction and US TV?!
