Financial consequences of taking the time I need

I'm really stressed out right now.  During the course of my life there was one thing I was always good at- making money.  Now I was never rich- but I've always handled my business.  Paid my bills, got by.  Borrowing money isn't easy for me, it never has been.  I've always been a workaholic.  Being a hard worker is one of the things I'm proud of, what I identify with.  That's why this is so fucking hard for me.
The past 8 months have been an emotional roller coaster.  I've allowed myself A LOT of license in the making money department.  I have a business for myself.  If I don't work, I don't get paid.  It was in October that J left me and I started to realize all I had to realize about my life.  I realized that if I didn't start making some major changes life was not going to be good for me- EVER.  So I've made those changes.  Now that's one sentence that describes A LOT of work, a lot of pain.  But I feel okay now. 
But my financial life is left in ruins- not as bad as it could be- but bad.  I have $0 in my checking account.  I have an overdrawn of $74 in my business account.  My dickhead of a landlord cashed a check dated may 1 on april 27.  Now- I don't think he screwed me on purpose (although I would never swear to it)- I'm sure he just didn't look at the date.  But- I feel like such and unbelievable fuck up.  I would have had that money in weeks ago if I wasn't so mentally fucked up for the past 8 months.
I know I had to go through what I did.  I know it was a necessary part of my life.  I'm writing this b/c I'm not just gonna leave work and say fuck it today.  I have to work through the stress and I have to keep doing so if I want to be successful in my career.  I have a stressful job.  I have people's life in my hands.  This won't be my life anymore.  I have finally faced all the past demons.  My job now is to absolutely make sure that I don't allow anymore demons into my life.  I think I can do that.  I can't afford not to. 
I have to forgive myself.  I forgive myself for not being financially solvent right now.  i forgive myself for not working up to my potential for the past 8 months. I know I had to take some time for myself.  I had to.  Life wasn't going to be good until I did.  I won't let myself worry.  I wasn't put here to be miserable.  Everything happens for a reason.  I'm not a failure just b/c I'm broke.  I'm not a failure just b/c I'm broke.  I know I'm not a failure just b/c I'm broke.  I gotta keep repeating that to myself. 
Btw- I have no idea why the font is different sizes in different parts of the post- that just happened.
