well RLE isn't an issue, I have been full time for quite a few years, and I have the paper trail for at least 3 years of that.... I would probably need to contact my old doctors who wrote my letters for Social security, dept of state, and DMV. I don't imagine getting that material would be too hard.
In fact it has been long enough, to where my current PCP doesn't actually understand that I am trans exactly (or maybe she does it isn't completely clear), see it is likely I suffer from an intersex condition, and since my previous doctor had that in the records when she asked me if I needed a gyno and I explained I don't have a vagina,ovaries, etc she just said "ah, I see". She then filed my previous prescriptions as per usual, including my hormones.
And as far as local support groups, there isn't one within 2 hours drive at least. I am in a very isolated part of IL. Chicago would be about 4 hours away for me, and being on medicaid, it is way too expensive for me to travel there.
I don't imagine it would be all that hard for me to find someone who could write me letters, but what doctor would take medicaid for SRS? I mean I have all Wpath requirements aside from therapists letters (After all I am very well adjusted, I have no need of ongoing therapy).
