and I was confused since I am not allowed to collect SS (teachers in CA have a different system). Then I realized when I read it that it was just a form about turning 60 and having all your retirement stuff taken care of.

Getting ssdi can be onerous

Whenever I get official mail from the IRS, etc I immediately get anxiety. I was debating having a glass of wine before I opened it.

I'm over it. You'd think I'm asking for a million dollars

I hate 'official mail' from any of them,,,, federal, state, county, city governments,,,,
I hate forms, I hate proving things, I'm just old & cranky anymore.

And three 8.5 x 11 functionality forms. One of the letters has something about scanning a big bar code on it

But each step is one step closer to the end of this. You’re doing great.

They said fill them out in pencil and bring them to their office.

Sounds like you have a good lawyer. Being proactive!!
