Ouch…Computer Death, I’ve had that happen to me too, several times, most recently 5 months ago, when my 4TB external drive decided to format itself to an unrecoverable state, and all my backed up data (and roughly 7 years worth of 3d work), was lost.
I wish you luck it getting back on your feet soon, being forced to start over is never easy.
I’ll gladly donate something on paypal as soon as i’m able.
