Faulty perception

I've found recently as I wean myself from sertraline that I am oversensitive and my perception is skewed.  I wonder if this is a commonality shared by all those who are or have been depressed.  As I battle a cold, weaning of meds and a pregnancy I've felt as though I am being bombarded with blame.  As if everything that goes wrong, or even slightly strays from the planned path, is my fault.  Is it?  No, probably not.  Do they blame me?  Realistically, probably not, however I have been the pillar of organization and strength in my family in the past.  Any lack of either falls on my shoulders, even when clearly out of my control.
Do you ever hear things like, "I guess I'll just have to cancel my appointment since you scheduled that activity then."  Is this blaming me?  In my current mind - absolutely.  I should have been aware of this schedule change approaching, though it was not ever made known to me and should have protested when we decided together to schedule the activity because of the knowledge of the other schedule change yet to come.  Make sense?  This confusing dialogue resulted in a total breakdown and a lingering feeling of hurt and blame.  I am failing at my job as mother, wife and organizer by having scheduled two events at the same time (though with spousal input) and have thus rendered my spouse incapable of attending his much loved event that just changed days this week.  Damn.  I could really use a crystal ball at this point to avoid screwing up things I couldn't possibly have known about.
Another such instance (also this week) was my decision (joint) to rent a movie and have a family movie night.  I had the audacity to do this with my spouses input when my spouse had forgotten to mention a co-worker's evening party.  Again, I really should have known that his co-worker was taking prelims. I should have called this person and asked if anything was planned so that I wouldn't again double schedule us.  Then, I should have called my husband to remind him to come home from said party when he was 5 minutes late, 10 minutes late, eventually over an hour late, rendering our movie overdue and our evening severely soured.  Again, totally my fault.  I am the time keeper and scheduler in the family.  I should have known that time would get away from my husband and been calling him... or would that have been nagging, leaving me in an even worse predicament?
These instances have been occurring in an increasing rate in my household.  Though each grips me with fear, blame and an intensity that leaves my sobbing, after examination they appear to be unavoidable unfortunate events.  Add the perception that comes with depression and they are all my fault.
