Hi waterknob, I'm sorry today was so hard for you
But maybe try to use that "you were doing so good for a while" as a bit of a positive?? You were doing so good, so that doesn't rule out you doing "so good" again.
It's just really good that you're reaching out for support now.........and maybe those "so good's"......can grow to be more frequent, last longer, and longer and longer and........in time.
Those people at work...........well let their attitudes remain their problems........if you can try looking past them as much as possible.......and take as much as possible from some of the parts of the job that are OK??
And as for reasons.........because you're you, because you're special, because you matter??!!
Although you can maybe think of some more too??!!
And don't forget we're here for you too!!

Alison
