How do I come back from this?

The full story requires like a decade of context, so I'll present this in tl;dr form:

Signed up for TEST

Ran into medical issues around ~2019, fell out of the game, was booted for inactivity (100% warranted)

Those who have been around for a while know what happened to TEST and the implosion that followed around 2020.

Nearly all my assets, including a FAX, carrier, and Rorqual (probably like 5bil+ worth at the time) were in citadels that are either LONG gone or no longer accessible to me.

The amount of isk required to get those items out of asset safety is far beyond what I can afford with liquid isk, not like I'd have a place to use capital ships without a corp anyway.

I've since recovered from medical issues, and the new freelance system that got announced recently is peaking my interest (god I hope it's used for literally anything other than scamming).

I also have 1 alt account with very high (at the time) research and manufacturing skills. Could make every ship in the game circa 2020.

What's the best, least-friction move to get back into the game?
